in the situation that is happening now, I think it is dangerous to trade on any site including the binance and Bitrix) but there is a very good security on Bitrix and it is very happy. polonich is also a good option)
Why you think Binance is dangerous to trade which is one of the most used exchange by crypto community for trading purpose.
Poloniex is the exchange need to avoid for now since they have lot of accusations were still open about them.
