I am trying to find some soins with passive income. I know that Neo generates gas, some coins have nodes.
What coins do you know with cheap nodes (less than 1k USD) or other coins that have staking mechanism?
I'd recommend that you check out COSS.io. It's a recent exchange based in Singapore that had an ICO last Q3 of last year.
They have a solid team and community and are adding coins regularly.
Basically, 50% of the trade fee in the exchange goes to coss token holders. You can store your coss tokens in their exchange to get weekly payout or store them in your eth wallet which you will link to coss exchange wallet.
You get the payout as exact tokens traded (kin, pay, etc) or if they are not eth based like btc, bch, dash, etc - you can convert them to eth - weekly.
Would recommend coss as well. Just get some coss token store it in your coss or eth wallet and just wait for your fair share of the fee and you get to grow your money. Plus it's slowly regaining it's value now that the exchange is growing. There's also pers on participating ICOs that are listed in COSS exchange if you are a coss holder.
