As you are asking about ETHconnect which is very similar to bitconnect, and loads of other Lending Platforms such as Hextracoin, RegalCoin Etc.....
Well they never end because the demand for lending platform is high, Due to them using MLM (multi level marketing) ie pyramid scheme and lack of general knowledge of newcomers to the crypto world.
These platforms are popular because most crypto youtubers promote them, the funny thing is they only brag about how much money they make off of their down-line which are the viewers who wish to earn such money.
Most of lending platforms has already exit scammed such as Gladiacoin, ControlFinance, Bitpetite and most recently Laser.online (which redirects you to bitconnect at the moment "Scam Confirmed!").
Don't take my word for it I mean I already did my research, and they are scams in my point of view. But I encourage you to research those platforms that I have mentioned above.
Thanks
Regarding control finance and bitpetite I made a you’ve video
Waring people at least two months before they went down and
In the same week control finance opened
I had proof on both but for eth Connect I think it’s a scam
I have fallen for but only a small amount of eth so no bother
Anyone readying or searching for ETHconnect please note
All signs point to SCAM
And wow regarding laser online redirect that’s interesting
