You can just hold OR deposit it into aave to earn 2.5% interest....but if you bought less then $1000 it would be recommended to bridge it to a L2 that would make it cheaper to use DeFi to earn yield. The easiest way to do this would be on uniswap just click ETH swap to ETH (BASE). Your Eth address stays the same for all ETH Layer 2s. Now for the yield part, The easiest way to earn yield would be to stake the ETH, and the most simple way to stake it is just to swap it for RETH (Rocket pool Eth) over time RETH will slowly increase in value against ETH at 3% apy and its a tax efficient way to stake since you don't pay income tax on the staking income you would get normally, instead the value of RETH increases because the staking payments go into a pool increasing your claim, and you only pay capital gains instead when you sell it. A complex but high yield method is to LP Farm on Uniswap, I recommend starting off with the USDC/ETH Pool
if ETH pumps and the RSI is over 70 then Split you ETH stack in half and set the custom price range to +-15%. If ETH continues to pump higher then your custom range (Lower chance of this happening) then your LP position will be mostly in USDC BUT you will have $1100 in USDC PLUS any fees you earned. IF ETH Dumps below your price range then you are left holding only ETH BUT it will be more then you started + all the fees you earned. If the Price crabs within your price range then you get pic related APYs, (keep in mind the APY in Uniswap is based on volume and changes daily) Also keep in mind that if you use a Large price range (+-50%) then you will earn less fees by ALOT compared to someone with a short price range (+-15%).
