Bitconnect is really the mother of all scams.
Perhaps, if Bitcoin falls 80% then we will see who had been swimming naked!
Just to be a little balanced, almost all cryptocurrencies have been called scams.
Steemit too, especially by a guy called Tone Vays. I would never have invested in Steemit when the yearly inflation rate was 100% av the power down period was 2 years. It do look scammish.
