When will this ponzi scam end? When it happens, many people will cry.
And the people here who turned those criers onto BitConnect late in the Ponzi will simply move on to the next Ponzi to start the process all over again starting with dissing those claiming that it's a Ponzi.
Following that way of thinking maybe you should stay home because yoy can brake your leg ;-)
Of course people will move forward if something goes wrong. Unfortunately there are many people who are promoting ponzi schemes on daily basis.
Personally i believe Bitconnect will be around long enough to make a lot of people rich.
Basic danger i see is that BTC will take a big hit and Bitconnect will follow the trend. I am not talking about price drop but some goverment moves for example.
