How many BTC bitcoin
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform mining: users can explore the computing power of different hardware on many platforms
The concept of 21 million
bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million

generation principle
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 10] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
bitcoin network generates one block every 10 minutes on average, and the reward for each block is currently 12.5. At the earliest time, 50 BTCs were awarded to each block, which was halved after 210000 blocks were excavated, about once every four years. It is expected that the next halving will be in May 2020, when the reward for each block will become 6.25

1-75: copper mine will be found in the birthplace
75-125: segenite in wetland, tin ore and igneous ore (in spider hole)
125-175: alx highland, Nano iron mine (walking along the mountains)
175-245: there are two choices
① in the three holes of Filas: each hole basically has 3-4 secret silver
② it is mainly concentrated in the east of the wilderness, where there are JY Dragons: there are iron, secret silver and real silver
you can practice until 245
245: go to the fat man hole above LM stronghold, there are black iron, Se silver and secret silver, A lot of them have been trained until 275
275: you can dig fuser silver and start to make money. Ha ha
there are also two choices
①: East plague, there are five points to brush fuser silver on the Internet, And the chance of getting out of arcane crystal is high
②: go to the hole of the three JY worms in xlss (LR DZ small D is recommended) and each of them has 4-6 fuser silver
after 300, you can mix in Outland to 375!
the risk of all financial procts is that after the depreciation of the financial procts, they may not appreciate or return to the price when you bought them on time
that is, your property is trapped in it, and you are unwilling to sell it after devaluation. Wait, I don't know that you can't get it back until the end of the year. Maybe, just like China's stock market, you can't stop losing. The more you wait, the more you lose
1.
is the solution of the equation. For example, one number of a function can only be 1, 0, and negative 1. Then there are only three finite solutions<
2.
money is only in the middle, and it has to be spent before it has value, so you are right about the second point. The loss of wealth
3.
it's possible that whoever has a big maker will follow him, just like the virtual currency now has a big bitcoin plate and a big maker
just for personal point of view, don't spray if you don't like it, thank you.
