The defi lending plataform was a good expansion using smart contracts, despite we know that several projects had been hacked and still got hacked these days, loosing milions of costumers money.
Its a profitable business for only a few projects around wich are able to have Bilions staked into them, giving their token as reward to boost APY... its funny if we consider this tokens value should be near zero, as they hadnt liquidity to get traded without affect the price.
Some projects decided to start with pretty low emissions, wich made difficult to get the coin and its beneficts, making it expensive, while others used the unlimited supply to boost and make their own token worthless...several aproaches had been done and well i havent found a balance yet.
We deposit btc, eth, bnb get some apy boost with those Defi tokens wich they capture part of the revenue generated from costumers, all deposits earn around 80-90% and the remaining is the protocol fee soo they are able to get revenue without have the funds, until liquidations happens, and if the protocol gets something from them.
I had tryed different of this projects and well its good if you dont wanna to sell your coins, or dont wanna risk into coins and wanna just passive income, but the risk still there, one mistake into the contract and funds will be gone...sure its better stake stablecoins into this DEFI lending then into the banks but the risks are bigger as well the potencial returns.
