Bitcoin is just a protocol. It was released in 2009
TCP/IP are just protocols that were released in 1972. You could call them the backbone of the internet. Look at how long it took us to get to the internet that we have today, where TCP/IP is the backbone.
Click here to read a bit about TCP/IP and blockchain technology.
HTTP is just a protocol that was released in 1991. You could call it the backbone of the world wide web.
SMTP is just a protocol that was released in 1982. And IMAP is just a protocol that was released in 1986. You could call these protocols the backbone of email. Many people used to say that email was useless and nobody would ever use it.
TCP/IP was actually developed by cypherpunks just like bitcoin, PGP, and many other great protocols and technologies. In fact, two cypherpunks by the names of Hal and Len actually lived near each other and both helped develop TCP/IP. And they are also two of the three most likely candidates for being Satoshi. But that’s not important.
People used to say computers and the internet was a useless waste too. Computers do use far more electricity than bitcoin mining. So perhaps they were right after all.
We are in the early majority. Bitcoin hasn’t had it’s Windows 95 moment yet, and I’ll explain that statement below.
Do you remember back in 1990 when everyone had heard of the internet but you didn’t know anyone who used it? This is much like bitcoin right now, and even less people use the lightning network. Both are still in beta. February 1991 is when AOL for DOS was released. AOL for DOS made the internet fairly easy for everyone to use. But you still probably didn’t know anyone who used it, and you probably didn’t use it yourself. The internet didn’t start getting popular until Windows 95 came out and most people still didn’t use it for more years.
I can’t wait to see where bitcoin is in a 12 years where it will be 23 years old. It was 1995 back when TCP/IP was 23 years old.

Bitcoin has the potential to be the backbone of the financial system. And that’s what people like the rocket scientist Michael Saylor are betting on. Michael Saylor is the same MIT graduate that predicted the mobile wave.
I want to inform you all that I am not a bitcoin maximalist. And my favorite cryptocurrency is actually an altcoin. I know you’re shocked to hear that. But bitcoin holders please fear not, because I still see bitcoin as the safest bet. And I also see bitcoin as the only protocol that has the potential to be the backbone of the financial system. If this happened, then companies and countries would be using on-chain payments to settle large payments. There could be bitcoin backed currencies (like gold backed currencies of the past) and even bitcoin banks. Hal Finney predicted there would be bitcoin banks in the future all the way back in 2010 Most people would be using second layer payment protocols to send bitcoin in milliseconds and costing almost no fees. And these second layer protocols like the lightning network take a negligible amount of electricity to operate. Bitcoin can scale to handle as much demand as the world can create because of it’s second layer protocols.
Satoshi didn’t create bitcoin to get rich. He created bitcoin to allow online payments to be sent directly from one person to another without requiring trust or permission of anyone else. Over 99% of altcoins were created to enrich their founders and over 99% of them have no future. None of them are as secure, as decentralized, or launched as fairly as bitcoin. Bitcoin has the most users, largest infrastructure, no premine, no developer fund/tax, no leader, longest track record, is the most secure, is the most decentralized, and bitcoins circulated freely for 18 months before ever having any monetary value which can never even be replicated by an altcoin because the genie is out of the bottle now. And unlike the founders of every altcoin, Satoshi never cashed out. The issuance schedule and maximum supply of bitcoin are both clearly defined and will never change. Bitcoin development is decentralized and anyone can contribute because Satoshi published bitcoin under the MIT license so that it’s open source and anyone is free to do anything with the source code. Bitcoin protocol rule changes are also decentralized because they require nodes to come to consensus.** All of this is why bitcoin is so vastly different than altcoins.
Cryptocurrency is full of scammers/grifters, ignorance, and people that actually believe the lies because they’ve been sucked into altcoin cults. Gamblers use altcoins for trading/gambling to increase their bitcoin stack or even their ETH stack if they don’t understand bitcoin and cryptocurrency, and they aren’t aware that Gary Gensler, the current Chair of the SEC, just said that „a lot of crypto tokens, I won’t call them cryptocurrencies for this moment, are indeed non-compliant securities” this week. And nobody told them that the SEC disregarded previous claims made by Bill Hinman, former director of the SEC’s Division of Corporation Finance, who suggested that offers and sales of ETH are not securities transactions. But enough about that.
Gambling on altcoins can be very profitable during a bull run because the altcoin market is basically a short term casino where you actually have a good chance of winning. It’s a relatively easy way to increase your bitcoin stack.
If you properly handle your private keys, then your bitcoin can’t be stolen or seized and nobody can stop you from sending it to anyone else.
Any protocol rule change that doesn’t make any previously invalid blocks now valid is called a soft fork. This would be a miner upgrade and is easier to accomplish, we can give the mining nodes a chance to upgrade, bip9 can be used, or the nodes can just run compatible software.
All protocol rule changes must be agreed upon by fully validating bitcoin nodes. Even if the mining nodes don’t agree, if the full nodes come to consensus and make a rule change, people will continue to mine as long as it’s profitable to mine, so the miners have to deal with it or piss off and other people will mine. The mining difficulty will adjust every 2016 blocks regardless. So when it comes down to it, only the users who run fully validating bitcoin nodes are in charge of bitcoin.
Fully validating bitcoin nodes must come to consensus on any rule change that makes any previously invalid blocks now valid, and that’s called a hard fork. This would be a pretty big upgrade, and it would be difficult to pull off with bitcoin because it’s decentralized. And that’s a good thing.
There is a maximum supply of 21 million bitcoin, and that will never change. Satoshi designed the protocol so that miners solve a block every 10 minutes on average. The block reward started at 50 BTC. The block reward gets divided by 2 every 210,000 blocks (4 years if the hashrate remained constant), which we call the block reward halving. The block reward is currently 6.25 bitcoin and the next block reward halving will happen around April 2024. And then the block reward will be 3.125 bitcoin. The mining difficulty adjustments every 2016 blocks which is approximately 2 weeks. So if it’s profitable for people to mine, then hardware gets turned on and the mining difficulty increases. But if the price of bitcoin lowers so that some hardware is unprofitable to run, then it gets turned off and the mining difficulty decreases. And as the block reward gets divided by 2 every 210 thousand blocks, the transaction fees will continue to incentivize miners to secure the network even when the block reward is minuscule.
Many users here like to repeat that the last bitcoin wont be mined until 2140. And while it is true that the last satoshi will not be mined until 2140. It is also true that approximately 97% of bitcoins will be mined by 2032, and the block reward will just be 0.78125 BTC at that time. But if bitcoin is worth, for example, a million dollars, then the block reward alone in 2032 would be worth more than the current block reward + transaction fees at this time. That’s not even accounting for all of the transaction fees that the miners will also be collecting from the transactions that they include in blocks.
Bitcoin is constantly being developed. Bitcoin also has second layer protocols that are constantly being developed and they don’t require any consensus. So anyone can just create second layer protocols for bitcoin and nobody needs to agree on anything. It’s up to the users of bitcoin if they want to use various second layer protocols that maximize the user experience. One of bitcoin’s second layer payment protocols is called the lightning network. It’s still in beta but it already allows an unlimited amount of users to send and receive bitcoin transactions in milliseconds for extremely minuscule fees.
Bitfinex, Okcoin, and Strike by Zap have already integrated the lightning network so that people can deposit and withdraw bitcoin using it and Kraken will be integrating the lightning network later this year. Kraken even has a US banking charter and Kraken Bank plans to offer most typical banking services later this year.
For newbies wanting to try out the lightning network: I only recommend you to use Muun wallet or Phoenix wallet. They’re both user friendly and they allow users to send and receive on-chain transactions or lightning transactions, all from the same wallet. BlueWallet is also a great choice but it’s more advanced than Muun and Phoenix.
Bitcoin has second layer protocols like the lightning network and statechains. The lightning network allows an unlimited amount of users to sent and receive bitcoin in milliseconds for almost no fees, and uses minuscule electricity. Bitcoin also has a second layer protocol called statechains that allow non-custodial off chain transfers which bypass paying transaction fees and waiting for confirmations. And statechains can also be turned directly into lightning channels at will. So statechains allow users to open and close lightning channels without performing any on-chain transactions, without paying a transaction fee, and without waiting for a confirmation.
Bitcoin is also switching to schnorr signatures and activating taproot this year which will improve privacy, security, and efficiency. This will also lower the operating costs of running a node and the transaction fees for exchanges by an expected 30% and it will also allow us to use many more second layer protocols that have been developed. This will also allow us to create massive multi-signature transactions that are substantially smaller in size, and will even allow users to aggregate all the multiple signatures of a transaction into one (multiple signers can produce a joint public key and then jointly sign with a single signature). Shnorr signatures and taproot will also allow us to use the coinswap protocol which is pretty self explanatory, the musig2 protocol which will allow aggregating public keys and signatures, new discreet log contracts which increases privacy and scalability minimizes the trust required in the oracle which provides external data for the contract, and point time locked contracts which will improve the privacy of bitcoin payments using the lightning network. Trustless cross chain atomic swaps should also be available towards the end of this year. Schnorr signatures also makes multi-signature and single-signature transactions indistinguishable on the blockchain so an observer will not even be able to tell if a multi-signature transaction or a trustless cross chain atomic swap has happened by viewing the blockchain. NFTs can also be done on bitcoin and that’s where they were done first back in 2012. There’s also various sidechains in development, including liquid network. There’s the RGB protocol which will allow smart contracts to be done using bitcoin on the lightning network. And much more.
Money (not fiat currency) always evolves in four stages (this is from the what is money? section of The Nature and Creation of Money chapter of a college course on Principles of Macroeconomics). Bitcoin is currently going through the second stage of the evolution of money, which is a store of value. The next stage is a widely used medium of exchange. Bitcoin may evolve into the third stage in 5 years, in 7 years, in 12 years, or bitcoin may never evolve passed the second stage. The final stage of the evolution of money is a unit of account. Bitcoin is also currently going through price discovery. Bitcoin’s true value needs to be found before it will ever be a widely used medium of exchange The lightning network also to be adopted by the users, merchants, and exchanges before it’s even possible for bitcoin to evolve into a widely used medium of exchange.
Sursa, aceasta postare de pe reddit care dupa parerea mea, puncteaza foarte bine ce inseamna tehnologia blockchain acum, si ce ar putea insemna in viitor, si implicit cea mai valoroasa crypto-moneda, bitcoin.
Si o sa mai pun aici un copy paste la unul din mail-urile dintre Hal Finney si Satoshi Nakamoto dupa ce acesta din urma a postat prima versiune alpha a bitcoin:
Congratulations to Satoshi on this first alpha release. I am looking forward to trying it out..
Total circulation will be 21,000,000 coins. It’ll be distributed > to network nodes when they make blocks, with the amount cut in half
every 4 years.
first 4 years: 10,500,000 coins
next 4 years: 5,250,000 coins
next 4 years: 2,625,000 coins
next 4 years: 1,312,500 coins
etc…
It’s interesting that the system can be configured to only allow a certain maximum number of coins ever to be generated. I guess the idea is that the amount of work needed to generate a new coin will become more difficult as time goes on.
One immediate problem with any new currency is how to value it. Even ignoring the practical problem that virtually no one will accept it at first, there is still a difficulty in coming up with a reasonable argument in favor of a particular non-zero value for the coins.
As an amusing thought experiment, imagine that Bitcoin is successful and becomes the dominant payment system in use throughout the world. Then the total value of the currency should be equal to the total value of all the wealth in the world. Current estimates of total worldwide household wealth that I have found range from $100 trillion to $300 trillion.
With 20 million coins, that gives each coin a value of about $10 million.
So the possibility of generating coins today with a few cents of compute time may be quite a good bet, with a payoff of something like 100 million to 1! Even if the odds of Bitcoin succeeding to this degree are slim, are they really 100 million to one against? Something to think about…
In poza de mai sus se vede o bulina mica roz, unde am vandut BTC, undeva in septembrie, cand m-am bucurat de un profit minusul, de vreo 11%. Dupa ce am vazut cat de mult a crescut, si dupa ce m-am interesat mai mult, am luat decizia sa cumpar si sa HODL.
16.05.2021: Ce fac eu? I Buy The Dip. Am cumparat pana acum, 16 mai 2021, bitcoin in valoare de 738.73 euro. 0.01740297 BTC mai exact.
20.05.2021: Am mai cumparat cu inca 91.77 euro, ajungand la 830.5 Euro investiti. Si un numar de 0.02013729 BTC. Valoare de 808 euro.
14.06.2021: Valoare totala investita in bitcoin, 4437.31 lei adica 901.98 Euro. Am in total 0.0226662 BTC.
28.07.2021: Valoare totala investita in bitcoin, 4884.88 lei adica 992.67 Euro. Am in total 0.02546918 BTC.
