The problem with Bitconnect is that even if it is a ponzi scheme many people in crypto will still participate on the basis that it is a gamble that they are getting in early enough to get out. Its almost like an online game people play. That said with the amount of money that is passing through Bitconnect; if it is a scam, they are going down yet there is no guarantee that users will be able to recoup their money. That is the catch-22 for regulators and users both.
