That is kind of the whole point of investing into a casino and that is why many people do it, because we do not have savings account in bitcoin world.
Hmm,,, that is a strange reason to want to invest. Savings account for me should not exist, that is the role of the bank, I want to have crypto I should keep it on my own and not expect "free money" as interest. I invest in bankrolls and I know the risk that comes with it. I know very well I can lose it if luck is not on my side.
