I am a small fish and only hold 100DOT

I can earn 15%+ on exchange staking it which I don't want to give up.

If you stake it in stake pools which set up by centralized exchanges, you will have to lock your coins in their pools and you won't know the exchange collapse like FTX. It is very risky and another risk from staking which is basic in DeFi is impermanent loss.

By staking, you have to lock your coins and receive staking reward gradually. Many things can happen with that project during staking time, also for the centralized exchange with its staking pool. That project can rug pull or will have high inflation. Staking basically causes inflation and it's not easy to control inflation with staking. Uniswap, Pancakeswap failed to control inflation in the last three years and their tokens lost value.
