if you want to be rich, you have to work diligently lol
some investors who have joined the world cryptocurrency save the profits invest in the bank, the bank is only a means to save or store someone's wealth. unlike cryptocurrency, cryptocurrency is a place to invest or make a profit in order to gain wealth. so basically banks and cryptocurrency can not be separated or used from one of them. banks and cryptocurrency can complement each other to seek wealth, but with a note you are good at playing or running a strategy.
Lol. Actually as funny as it sounds, it is just the truth. Money do not grow on trees and you have to work for it, and even though some may have gotten lucky by keeping some little money in bitcoin over the years and watch it increase, relying on just that alone could still have made them screwed.
However, investment is all that is going to make you wealthy and not keeping money in the bank. All investment comes with a risk or the other, and it is left for you to know the level of that risk and be able to minimize them. No risk no gain !!
