Lending and bot trading is a no go for me.
Damn too risky and with lending information leaks. I don't like that idea even if I am the lender.

Bot trading have so much issues. You could get it wrong and all your capital will go down with it.
Staking is a good idea but it takes time and same with open trades.

I guess I will choose staking since open trades could be difficult and you might get bored with it. 
With staking you could add more funds for a better return. Yeah, staking it is.
