Bitconnect bilked people of a shitload of money claiming to invest in bitcoin/cryptos. By posting this video, you are implying that the underlying asset class used in this scheme (cryptos) is financially unsound.
Bernie Madoff bilked people out of tens of billions of USD with a stock-trading Ponzi scheme. Does that mean that the underlying asset class that Madoff professed to trade in (stocks) are also financially unsound?
