I am not a big fan of Bitconnect in general. Their lack of transparency on their said-to-be trading bot, their hidden leadership/team behind the project, their MLM tactics to bring in new (inexperienced) users onto their platform, their aggressive use of PPC advertising to again suck in new people to the space, their top-tier marketers which tend to care less about their down-line and more about their referral profits, and their followers blind trust in the platform (so much so that people are hyping their new ICO without even knowing a single thing about WTF it even is, such as Craig Grant telling people to buy it without question and then 2 seconds later talking about how he has no idea what it even is... which is a VERY dangerous mindset to have if you ask me).
It may or may not be a ponzi scheme, but either way I find their are better and more trustworthy investment choices within the crypto space, and personally Bitconnect will never see even a single cent of my money.
Just my 2 satoshis...
