I believe bitcoin and banks are well renounced investment platforms but many people prefer bitcoin investment despite is very risky because of high demands and rising price interest and banks on the other hand saves millions of people finances all over the world yet their investment interest is very small but less risky than bitcoin. Which do you preferred your money to be save in as investment? Bitcoin or bank! What's your reason?
I pretty much agree with you, there could be many reasons but I think if you have capital and know how to use it, well than it is better for you to invest it in trade. See, you will invest your capital somewhere, if invest in bank then you have to get some package for that, it will be long term investment and banks are according to their law. It is right that you should invest some your capital, but keeping in mind today trend and E-commerce, BTC is the best platform for you to invest and get more profit from time to time. But, before this opportunity, you should learn first about trading, than surely you will get success.
