I've put my money in a couple of 'exchange shares' type tokens.
KuCoin Shares (KCS) gives you a cut of every coin traded on the platform, which is great since they often hold competitions for who can trade the most volume - and kucoin is known for early adoption of coins such as deep onion so your passive income has speculative potential too. Added bonus that you get compound interest from people trading KCS but raw ROI is only 6% ish.
The other one is Cryptopia Fee Shares (CEFS), which gives you about 10% 15% annual ROI, all in BTC, LTC, NZT and USDT - which means you don't get a ton of dust like you do with KCS.
I'd be careful with that NPSX one, you get a passive income but I held too long on a coin (BTX) with a similar airdrop model and it dumped from $30 to $5 in a matter of days since people freaked out as we got closer to the end of the airdrop supply.
Never heard of CEFS but I will look into it. Thx a lot.
6% sounds not this exciting in this space...especially if you have dust but I am looking more into exchange tokens atm.
NPSX I was part of the ICO because I like the project.
It is usually the same with airdrops big spike before and hard sell off after.
I dont know BTX but seems like it took a nosedive before the big correction this year. I keep an eye open.
Thanks for the comment helped a lot
