To be honest without insider information there is no way of knowing if Cloak is genuine or a bunch of script kiddies taking us for a ride.
In short Cloak (and all alt-coins) is very high risk investing. Dont' invest what you can't accept losing.
I've learned from this experience, let greed get best of me to an extent and put in more than I should have. won't be cashing out though. Don't see the point now. I'm going to HODL and hope Alty is real deal.
