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.
I don't if that is right but I'm not unto investing my money just because I don't have any bank accounts around the world but I think the most important their is we have a account and use this whenever we need to invest on something like putting our money on casino investment or anything what we think good for our money. And if you want to go crypto then personal wallet is enough since you could decide to wait for a pump and earn on it.
