Cryptocurrency, will help you in the long run but cant rely on it unless youre a professional trader, arbitraging or day trading. I also got in right at the peak :) but have understood and learnt a lot in the last few months.

Besides steemit, you should look at airdrop channels on telegram and check out cindicator app. They have monthly payouts in ether if you're good as a crypto analyst and have some idea of how markets work. Steemit is definitely great but requires investment.

There are many passive income ideas using cryptos.
