"As long as people keep investing and new people are signing up their token will continue to rise sharply."

^That is exactly how ponzi schemes work. The question is what happens when people stop investing and want to take their money out because they are scared (due to say....a website failure/hack or something like just occurred?)

I also don't believe they are using a bot and it is probably just experienced traders, but they are claiming they are "profiting from Bitconnect trading bot and volatility software" on their website. It is a highly dubious claim at best.
