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.
I don judge their decisions despite all given facts. Prices can stay over 10000$ level for a long time or it can hit low levels like 5000$ if there is bad news for cryptocurrency community. Let's wait and see who is smart and who is not.
$10,000 is only a small target for the growth of Bitcoin in future.
Bitcoin can reaches this target as long as the cryptocurrency market still keep the bullish trending in next few years.
However, be careful the bubble of cryptocurrency, nothing guarantees this bubble will not burst someday.
