Defi pools, liquidity pools, staking reawrd

Today we have got situation that many Ethereum holders and Ether-token holders put their tokens on DeFi platforms, liquidity pools to earn interest…This make sense because Ethereum is still POW network and holders cant participate in staking…
OK…tomorrow we will see this services on Cardano network (DeFi-s, liquidity pools …). But this services must give greater reward to Cardano user than 5-6% because this is the only way to attract users to participate…If that will be true, we will be witness of massive moves ADA from stake pools to that pools…who will than validate ours transactions…:-)))
