Bitcoin too much risky than the bank to invest money. But you can make a lot of profit to earn from bitcoin. Bank is a safe when you want to safe money but the interest is too small and too slow to become a pretty much good interest.
Everyone knows that bitcoin investment is more risky than investment banks, if we invest bitcoins then our money can be lost anytime, while investment banks get guarantees from the state, but I never fear the risk so I will make bitcoin as an investment.
