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.
will not be at risk if you already understand bitcoin and ask the same thing that has more experience in bitcoin. The current price of bitcoin tends to rise so that this price increase will give you an advantage, even though bitcoin prices are down several times but we can see on the bitcoin price chart even increasing drastically that is what makes bitcoin appeal more than any other investment. If you doubt you will not be able to develop and if you progress without thinking for a moment you will lose.
