With the current price of bitcoin so high i do not see that it is a good way to invest your money at this time because a crash at this time would dent your bank account and it will hurt real bad ,i would be happy to invest in other coins which are not too high rather than investing in bitcoin at this time.
But bitcoin price keeps going up if you intend to invest for long terms. Investing in bitcoin now is yes kind of very risky because there could be a crash on its price. But if you it as a long term investment, for sure you will earn a very good income.
