You must know the differences between the two because in bitcoin your money will grow very high but the risk is very high but the good to this you can earn a lot of money that you will  never experienced in the banks who gives a little percentage of your money that you deposited to them but it will keep your money safe. I suggest to invest a money if a person have it because of the inflation let say you save more money to the bank but after years goes by the value of it is decreasing but if you put on the bitcoin it will grow.
