thanks for the information, this is an accident for bitcoin, and in the end, the public will judge bad bitcoin. public and investors will not be interested in bitcoin, and bitcoin gets red trust from investors, so bitcoin spreading will drop drastically, and bitcoin will be dying.
and it will be difficult to rise again.
The above incident is nothing to do with bitcoins because they were running a fraud scheme but they just choose the cryptos as a payment option because of easy and anonymous transactions. Even those guys ask for other means of payment also some people might have invested in these HYIP or multi-layer schemes. Nowadays everyone wants easy and fast money but if they get scammed then blame it on a technology instead blaming themselves for not thinking enough to make a vice decision.
