95% + responses of most people seem to say they will devide their BTC for Trading, cold storage, casino gambling, Holding etc. So no one is prepared to go all in on one form of investment?
no because 20 bitcoin is 15,000 USD and no one is so eager to lose it all in one place. and we all know that any kind of investment comes with some type of risk no matter what kind of investment it is.
so that is where diversifying comes in. you invest in different things to reduce the risks of losing.
although i should add that in some rare occasions specially since 15K is not really a very huge amount, you can go all in something that you feel 99% sure about and thing it will reward you.
