Although Fang's father and Fang's mother don't know what Bitcoin is, they know the Internet, in recent years, smartphones have been popularized, and they have used the Internet to check information and watch videos, all of which are used by thieves, although they don't understand what algorithm and P2P mean, but they are generally clear about what Bitcoin is.

In the Spring Festival Gala of 03, Zhao Benshan performed the sketch "Heart Disease", Fan Wei won 3,000 yuan, he was excited, he gacked, and he was finally discharged from the hospital for treatment, and won the lottery again, winning the 3 million grand prize. So he suffered from heart disease and almost hiccups.

Although Fang's father and Fang's mother have a strong ability to bear it, they can't help but feel pounding in their hearts, 70 million, it doesn't sound like much, but if it is calculated according to Fang Yuan's salary of 10,000 yuan a month, then if he wants to earn 70 million, it will take at least 583 years, if it is calculated according to the age of 80 in his life, then it will take eight lifetimes to earn so much money, but now Fang Yuan has done it in a month's effort.

Fang's father and Fang's mother leaned on the sofa, stroking their hearts, feeling a little unbearable, the little guy went over to help very intimately, and exhaled in his little hands, thinking that this effect was better, because every time she fell, the exhalation would not hurt.

The grandparents were amused by the cute and heartwarming little appearance of the little one, and felt much better.

Fang's father was the most sensitive as a policeman, and after calming down, he asked, "Can this bitcoin be used to buy things directly?"

Fang Yuan shook his head.

Father Fang thought for a while, and said with some suspicion: "How do I feel that this is like a scam, and it is of the same nature as pyramid schemes and illegal fundraising." "In the late 80s and early 90s, illegal fundraising was rampant among the people, and in recent years, Fang's father has personally caught a lot of various pyramid schemes, so he still knows a lot about them, and to put it bluntly, they all belong to variants of Ponzi's scheme.

The birth of any currency is endowed with value, but Bitcoin does not, and all its value is magnified in a game similar to beating a drum and passing flowers.

As soon as Fang's mother heard that it was a fraud, she became nervous and said worriedly: "Will this be illegal, otherwise you will return this bitcoin, and we don't want this money." "Although wealth is moving, it is still not as important as his own son.

"Mom, it's not illegal, transactions are allowed on the Internet, and some countries even recognize its existence. Fang Yuan knew that Mother Fang was timid, and he didn't know how to explain it for a while.

"Then how does your father say it's fraud, isn't fraud a crime?" Fang's mother is still very worried, other countries are legal, it doesn't mean that China is legal, and the United States is still legal with guns!

Fang Yuan thought about it for a while, and explained to Fang's mother in the most popular language: " This bitcoin is similar to beating a drum to pass the flower, but this flower is not only one, it has a total of 21 million, and it is still buried in the ground, when the first person digs out the flower, it is passed to the second person, and he asks for 1 yuan, the second person passes it to the third person, and asks for two dollars, and so on, the original worthless flower becomes valuable, the market price you just checked is about 70,000, that is, after endless transmission and speculation, and finally formed a market price. ”

"But this flower is not one, so someone went underground to dig a flower, but he could not be sold according to the initial 1 yuan, it must be sold according to the market price at that time, so everyone saw that it was so profitable, so they rushed up to dig, and soon buried in the top layer of the flower dug up, everyone continued to dig down, but the speed is getting slower and slower, so they hire more people to dig, this is the mining machine, the hiring is to pay, that is, the electricity bill, as more and more people dig, the deeper and deeper, the more difficult it is to dig, the cost is naturally higher and higher, and the flower is more precious。 ”

"It turns out that there is a cost, so where is your cost, just the computer at home? And the electricity bill is not much this month!" Fang's mother heard this, and she understood a little.

"This is what I just said about the algorithm is powerful, other people's mining machines are equivalent to small iron picks, but my algorithm is equivalent to excavators. Fang Yuan said very proudly, he didn't dare to say that his excavator was borrowed from someone else's workers to drive it.

Listening to Fang Yuan's explanation, Fang's father and Fang's mother finally knew what Bitcoin was.

"I always feel that this thing is a bit empty, so you better not do it. Fang's mother was still a little worried.

"What are you afraid of, I don't have a cost anyway, I earn if I dig it, and I don't lose if I don't dig it. ”

Fang's father and Fang's mother looked at each other when they heard this, as if this was really the case, there was no loss, if you dig it, you will earn it, and it doesn't matter if you can't dig it, you won't lose anything!

"In that case, let's dig for a year and a half. Fang's mother figured it out, and immediately slapped her big leg and decided.

“......。 ”

"Mom, this bitcoin is equivalent to a big cake, I'll drive an excavator to dig out some of it, but if you dig too much, those pickaxes will be unwilling, and something will happen. And the further you go, the smaller the number of outputs, the longer the time, and the gains outweigh the losses. This is also the fundamental reason why Fang Yuan decided to only dig 1,000 pieces, which is not much compared to the total plate, but it is already a lot for himself.

"You're right, you will accept it when you see it, the benefits are too great, and there will always be some people who will take risks. Father Fang seemed much calmer, and very much agreed with Fang Yuan's approach.

Lan Caiyi had been listening silently beside her, she knew that what was precious was not the 1,000 bitcoins, nor the excavator, but the algorithm mentioned by Fang Yuan, which was really valuable.

"Well, in fact, 70 million is a lot. Fang's mother comforted herself, it wasn't that she was greedy, it was mainly because a mountain of gold was placed there and moved casually, and no one was willing to leave it, not to mention that if he had money at the beginning, Fang Yuan's grandfather would not have died depressed.

"You got such a large sum of money, what are you going to do?" Father Fang had calmed down and asked casually.

"What are you doing, what should you do?" Fang Yuan was a little surprised, could it be that he couldn't fly with money?

"Something that has no interest, you got such a large sum of money, and at a young age, are you ready to live happily?If that's the case, I'd rather you didn't make this money?" Father Fang scolded angrily.

"That's what I said, isn't making money just to be happy, otherwise what are you doing to make money, I'm going to get this money, in addition to helping Chen Chao see a doctor, the first thing is to go to Luming Mountain to buy a villa, facing the sea, spring is blooming, hehe. Fang Yuan felt that this plan was too perfect.

Fang's father and Fang's mother were silent when they heard this, this was also grandpa's last wish, Fang Yuan helped him realize it, what reason did they have to stop it?

But Lan Caiyi didn't know, so he said: "Actually, I don't think you should be in a hurry to buy a villa, you can use this money to build a machine production factory, specializing in the production of your sweeping robots, in a few years, your money will at least multiply more than a dozen times, and it will not be too late to buy a villa then." ”
