No need to ask of it's safe because you will still use it if you have btc there and they not scam you,There's a lot of accusation in different exchanger here like poloniex,binance,bittrex and etc. but i still have my btc there so it safe then i don't withdraw my btc because i don't experience scam but if they do that to me i will find other like i will change trading site and not use their site anymore
I agree with your opinion, I think if indeed they are a scamer they will definitely close the market and replace with a new name. no exchange scamer site that can last long
