Everyone makes mistakes to begin with, BitConnect was even on my consider list for a while, but fortunately the price never corrected enough to take the risk ;-) Personally I think this is a lesson learnt to not have "all your eggs in the same basket", instead diversify your portfolio. For example I'm currently holding Zcash, Zencash, DeepOnion, as well as other privacy coins, as they are projects I believe will do well, but ultimately I don't know whether all or only one of them will go far. After seeing what happened to Verge, you can never know what will happen.
