Yes,if you invest your money in bank it won't make you rich so better invest your money in bitcoin because there's a great chance that you become rich in here.
honestly pal its not like that IMO, 'cause indeed banks is the most reliable place which we can put our money without doubts unlike online wallets. But you have point which is much better to invest on bitcoin rather than keeping our money on banks because it will not grow on banks honestly. so much better to dump some and make some investment to earn profits or to multiply our money.
