Banks are earning big profit from our deposits, they earn bigger than the interest that we get from our deposit because they put a bigger interest rate through thier borrower's or lenders, i think bank is not too far from big whales in crypto they buy or collect coins in dip and they sell in bull and they earn bigger from the holders that sell at loss they are almost the same or what? What dou you think?
I don't know how OP do this, but OP clearly explain two totally different things, but then OP make the conclusion that both are the same. Bank take our deposit and lend it to their client, get the interest from that loan, thats true. While crypto whale buying in the deep to raise the price, and then sell it to people who are FOMO, similar to your explanation and that is totally different of what the bank does.
