Still I feel we need something like a bank to deposit our crypto currency and get interest from it. I heard about some websites. But difficult to believe in those now. Any legit ways to get interest in crypto currency deposits ?

you have staking in some coins like when you stake NEO you earn GAS coins. Earning interest will evolve and the market space is/will mature to show a safe way to earn and not be a scam.

we have been conditioned to believe in the corrupt non transparent banking system that is a centralised control so why would you want to put decentralised currency with a bank? When you deposit fiat money into a bank its not yours any more and if they wish not allow you to withdraw you cant do anthing about that.
