I use this exchange to trade REV tokens because BTC-Alpha supports REV TRC-20 token deposits and the trading volume is fairly good. I trade here every week and I didn't face any major problems, although once my REV token deposit got stuck but their support was so good that my token was added to my account within 10 minutes after talking to the support team.
Trading fees and withdrawal fees is competitive, I withdraw from BTC-Alpha to XRP coin because it is the only coin whose fee is lower, although BTC-Alpha supports Fiat currency and you can withdraw in Fiat currency if you want.
Overall, I can honestly express that this exchange is unquestionably protected and you shouldn't have any sort of issues with them.
