The problem here is for how long will you get paid? I've put over a thousand dollars in project with low interest every month, it fluctuate just like you said and after few months no more payouts, it's one reason I can't trust staking websites
That's true man, I have my doubts too even if I am trying it now.
They claim that there is a smart contract element that allows them to feed buyer and seller hence no centralization, but how do we check?
