exactly my concern also they need a reputable exchange. I think it's a dark horse but it's expensive to move safex as it uses bitcoin blockchain at the moment. Whitepaper has been some sort of super secret and the project has been mishandled to this point. If they can get listed again somewhere such as binance and produce a white paper. I'll consider buying safex again, but at the moment it's hands off for me. The potential short and midterm profit is not worth the agony. They were delisted by bittrex for good reason.
