Xu Zhe applied for a QQ number and copied it on a piece of paper. Call Song Xingye again, read out the number, and ask her to write it down as well.

Then I heard Song Xingye say: "Okay, if there are any problems in the future, we can use QQ to discuss." ”

Xu Zhe was a little puzzled: "Why do you use QQ to discuss problems?" With so much time in school, it's good for you to ask me in person? ”

Song Xingye: "......"

After waiting for a few seconds and not hearing the following, Xu Zhe asked, "Hey?" Is it still there? ”

Song Xingye: "I just want to say, if there is a question I forgot to ask in school, I can use QQ to tell you." ”

Xu Zhe: "Yes, but you don't take a break after school?" If I were you, I could use the computer casually, and I would definitely concentrate on playing with the computer, so why would I think about any problem. ”

However, Song Xingye seemed to have caught some loophole, and immediately said: "No, I heard Fei Fei say that you have a game console at home, but you don't play it yourself, and you always bring it out for her to play." ”

Xu Zhe: "That's a PSP, it's not the same as a computer. ”

Song Xingye: "What's the difference?" Don't lie to me, you must be secretly studying when no one is around, and then at school you can pretend to be 'what is there to learn about', right? ”

Xu Zhe: "You think too much......"

Song Xingye: "Don't try to lie to me, I've seen it all." Well, if I look for you in the future, I will definitely ask questions about learning. If you don't respond, you don't want me to catch up with you, and you just want to learn by yourself, right? ”

Xu Zhe sighed, and then couldn't help but want to laugh.

Song Xingye's words are really a bit childish, and they are also the kind of childishness that belongs to good babies and good students.

"Okay, that's it, I'm going to add your friend now, goodbye, good night!"

After the girl finished speaking, she hung up.

Xu Zhe put down the phone with a black line on his forehead. He felt that the girl seemed to have some subtle misunderstanding of herself. And he can't explain it yet, the explanation will only get darker and darker, making him really seem like a scheming tyrant.

Back in the bedroom, Xu Zhe took out his laptop again and continued to write the English email.

[Dear Mr. Nakamoto, Hello. I'm very interested in your idea of a currency, and I'm very happy to see that you actually put it to life. I understand that this is just the beginning of everything, and I want to be one of the thousands of practitioners. Even though I'm only a middle school student and may not have a strong technical foundation, I was able to do everything I could to learn......]

Of course, Xu Zhe has no special beliefs or feelings about Bitcoin, but since he wants to be a hand-reaching party, of course, he must shoot a good sycophant and play the role of a small fan online.

To Xu Zhe's shock, he received a reply only a dozen minutes after the email was sent.

[Hello, young friend. I'm glad you have such a strong interest in Bitcoin. The value of money stems from people's consensus, so in my opinion, your approval is precious. As it happens, I've prepared a document to help possible enthusiasts who can help you configure the environment for mining Bitcoin......]

Along with the email, there is a document that fully explains the entire process required to mine Bitcoin.

Of course, if you are a pure novice with no computer foundation, this document is basically difficult to understand. But for Xu Zhe, this is completely enough.

Staring at the screen of the notebook, Xu Zhe couldn't help but take a deep breath, trying to calm down the heart in his chest that was beating faster and faster...... But what do you think about it, the creator of Bitcoin actually replied to his email with a step-by-step tutorial? How does this make people calm down?

A sense of being part of the historical process arises spontaneously.

Although the night was getting darker, he was more and more awake. Just using his ordinary laptop, he got the mining configuration according to other people's instructions and excavated!

Finally......

"That's it!"

Xu Zhe couldn't help but jump.

The essence of mining is to solve mathematical problems. It's like having a banknote in the system, and as long as you guess the number of the banknote according to the clues given by the system, you can get the money. In this minimalist example, Bitcoin can be understood as this banknote, and guessing the number is mining.

In the last life, when this thing became popular, people participated in the number guessing game all over the world, and it was very, very difficult to guess faster than others, basically to the extent that ordinary people didn't need to think about it at all. But now that we are at the very beginning of our existence, and those who participate in this game can count on both hands, the difficulty is completely different.

Xu Zhe managed a block and got 50 bitcoins.

Based on the experience of his previous life, he knows that Bitcoin itself has indeed never been hacked, but the platform where Bitcoin is traded has blown up more than once or twice, causing many people's Bitcoins to disappear. But the 50 pieces he dug up were different - they were not put on the trading platform, they were not traded with anyone, they just lay quietly in their personal accounts, and there was no risk.

The cost of these 50 bitcoins is negligible.

And for the first time in nearly four years, the state will ban financial institutions from buying and selling bitcoin. Before the ban came down, the price of bitcoin had risen to more than $1,000 per coin. In other words, 50 bitcoins, sold at a high point at that time, will be converted to four or five hundred thousand yuan in domestic currency!

Of course, even more exaggerated is that eight years later, Bitcoin is nearly $20,000 a piece. If the 50 pieces in Xu Zhe's hand are sold after eight years, it will be more than 7 million.

And because it is an anonymous transaction made over the Internet, except for a slight hassle from bitcoin to dollar to domestic currency, the whole process is basically free of legal risk. For others, the biggest risk of playing Bitcoin is price fluctuations, but he is a reborn.

Like, now there is no need to struggle?

When Xu Zhe turned off the computer, he was a little dazed. About the future, about wealth, so many numbers swirled in his mind, making people seem to have no real sense of everything in front of them.

He picked up three pieces of paper and pasted them on his laptop, under his desk, and on his bookshelf.

The note reads the private key of his Bitcoin account — as long as he has it, he can log in to his account and trade Bitcoin.

Xu Zhe was afraid that he would remember or forget, so he simply copied three copies.

Then he lay down in bed, only to find that he could not sleep at all. And as soon as I opened my eyes, I found that the sky outside the window was cloudy.

The young man muttered to himself: "This thing really affects normal life......"
