I was lending on the Bitconnect platform for 14 days before they closed up shop, but it does seem a bit suspicious. There doesn't seem to be any verifyable proof that there is any real substance to it. I like the lending concept and sometime in the next month, I'm going to fund my Davorcoin account. I will ride the wave as far as I can and hope for the best.
So far, I feel like staking and trading are the 2 most stable methods to make money, but I just found out about airdrops and I'm pretty excited about that too. I feel like a kid in a candy store in this industry.
