I don't know what should i call them crazy because there is high uncertainty in the market of cryptos or should i call them smart because no doubt crypto will rule in future. This extreme level of trust is seriously amazing, either they will going to create a history after winning or they will going to be a part of history after loosing everything.
They are crazy no matter how you look at it, I believe that bitcoin is the future, but I'm not going to risk my entire life savings on that, I have some money invested on bitcoin and if bitcoin reaches its full potential I'm going to earn a lot of money, but risking everything is a huge mistake, what if bitcoin is banned or if bitcoin is replaced by a new crypto then they are going to lose all their money, efforts and time.
