is it risky to turn all my money to bitcoins? anyhow this money sits in the bank and do nothing for!
Yes, it's risky to turn all your money into bitcoin. Bitcoin is volatile and if you know what you are entering you understand the risk that you'll be taking. And if your money is just staying in the bank and earning with a very low interest better to take the risk in bitcoin by buying at dip and wait for it to grow. The profit in bitcoin may grow in lesser time than your expectation. More risk, more profit but invest only what you afford to lose.
It is, for sure! Bitcoin, or cryptocurrency in general, is already risky to begin with, and the fact that you are using "all" your money, perhaps your savings, makes it so much riskier that it already is. Although I agree that in the cryptocurrency market, every venture is some sort of a leap of faith, you still make calculated risks and not risk everything because once you lose it, it can't get it back, or not easily for that matter. I think if you are a started or a newbie, you should try it little by little, and invest part by part, instead of investing it in one big time.
