yes, it is very risky if you turn all your money into bitcoin but if you know what you input you will understand all the risks you will take. because if your money is just kept in the bank and only get very low interest I think more it's good to take the risk in bitcoin by buying bitcoin and wait for it to grow, because the benefits on bitcoin can grow in the lower time as you expect. more risky also the many advantages we get because everything there will be a risk we must take.
