You opened the digital currency exchange, and now I tell you that one of the unknown altcoins will double in the next ten years. If you study, you will have wealth and freedom within ten years. Do you believe me? Do you bet on houses and cars? I guess you dare not.
Don't say you dare not, 99.9% of people do not dare, because the probability of losing the bottom may also be 99.9%.
Therefore, the same is true of Bitcoin ten years ago. Few people know how the price of this thing will develop in the future, only a very small number of people have the courage and luck to get it today. But you are not such a person. Even if I asked you to start buying bitcoin ten years ago, you would never dare.
