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.
And you can't sleep when you see there are more than 10 people took loans from you that haven't paid yet. That is something that you might just need to call every hour when the due date is almost over. Its not like doing it offline where you can send your best goon to knock the doors of your loaners.
Staking is good, requires a lot of funds but somehow profitable unless the project ends not the way you expect. We've seen this happen already with Minexcoin.
