If there's a bad review on a review website then you should just stay away from it even if existed for many years already and also it is a cex but if you still want to use then then withdraw your crypto right away after you are done what you are doing.
It would seem that Trustpilot is not trustworthy when it comes to reviews. Look at the Binance, Mexc or any other cryptocurrency exchange reviews. Either 2 stars or lower. CEX is trash yes, but how can the reviews all be bad? And why does TP delete some reviews but not others?
Rather than a review website, it seems to be more of an extortion website to me....
I think it's still a review website but the only difference with another review website is that most of their reviews are biased in which most of it are paid. I think it's because that the reviews that are deleted are no longer profitable for TP that's why it is deleted. It doesn't matter to me anyway since I don't really use their website to check for ratings and such. Not really sure if my claim is true as I don't have any evidence about it that's why I check different review website and compare both information about a website.
