Bitconnect and before that Leocoin and all were all following this method and so are the others that pop up everyday. If you want some legit Lending platform look at SALT and EthLEND.

I have a little ethlend coin..but my invest in lend is down dramatically, i have more than $3000 in lend,and now it's just $1200...
BTCjam is one of long time lending platform or Irfanpak is person who is lending service more than 2 years via this forum alone. You may use either this site or him. There are many people still providing the service for lending and making more money with that.
But going behind all the lending platform means you are stupid. Like doubling and cloud mining. This lending platform also comes with the many ponzi schemes.
