I've always found it suspicious when looking at their volumes compared to other large exchanges such as binance. What would be the reason behind faking volume from a business's perspective? and how does that make a difference to us as the users?
large trading volume will attract some people to make a purchase there. Sometimes they make a fake wall to increase the volume.
Always be careful with the exchanger, I make sure the safest place is your wallet, and you have full access to your own wallet.
