What should I do with ETH winnings?

So I hit big on Stake, withdrew to my cold wallet. Not putting it back into gambling.

Current setup:
- 6.2 ETH in Ledger
- Basic crypto knowledge
- Gas fees scare me
- No staking experience

Options I'm considering:
- Stake on Lido
- Hold for next bull run
- Trade for BTC
- Convert half to stables
- Try yield farming
- Just cash out

Main questions:
- Best staking platform?
- Hold vs diversify?
- Good entry for yield farming?
- Tax implications?

First time holding serious ETH. Want to make it work beyond just hodling.

Priorities:
- Not losing it
- Passive income ideal
- Medium risk tolerance
- Long term growth
