That's just like putting all your money in a gamble. bitcoin's price changes rapidly and you cannot predict when it rises and falls. and it's not just on bitcoin. Investing all your money on one stock is a very risky move. You should invest just a right amount (maybe a third or a fourth of your money), and see how it grows first. If the results are fine, you can then try to invest a bit more money, but you must never try to put all of them. Don't be too reckless to do that.
