USI Tech is another blatant one. I am also quite concerned about Tether USDT and Bitfinex but those are not so blatant and could yet prove to be legit.

I have been looking at Davor coin like I said above and they seem to be also. USI Tech is another one that seems to be a ponzi scam but I think they already shut their doors. Have some people I know that so far after USI TECH stopped doing business in US and Canada they have not gotten any of their BTC or money back.
