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.
If you enter any investments or business, risk is always there. What we must do is to minimized those risk factors if can not be eradicated totally.
