Right now I have been finished staking off some coins. Because the profit seems too nice, but at the end, you can only get your return, if your lucky, but most of all users have been in a negative return.
That's the result if you are investing/staking to the coins that are not too popular. The estimation that the sites like masternodes.online is not reliable all of the time because the market is changing from time to time.
And what's worse than this? you can be a victim of a scam coin that's running themselves in a staking to attract more investors. It happened before but I can't remember those coins but there's always a way to search them online.
