First of all, you supposed to post the full URL link for us to know if the site is fake or the original. The original site is coinsbit.io which does not have a good review on Trustpilot.
This Exchange used some trick to fake the daily trading volume so they could rank up at Coingecko and Coinmarketcaps ( there where i foud them )
If the trading volume is not verifiable, coinmarketcap will indicate that. I do not think the trading volume is not true, but there service may not be excellent or good the way you want it and that is the reason for reviewing sites.
With the revie on Trustpilot,
https://www.trustpilot.com/review/coinsbit.io, I will say you should avoid such exchange.
Why don't you try exchanges with better trust score, like not less than 9 score on Coingecko:
https://www.coingecko.com/en/exchangesAggregator sites are not sufficiently likely to detect moderated trading volume, and that is not the first reason to conclude that the exchange is good overall so you can easily send assets to them.
Trustpilot is a review site which I think is what you are talking about too. If you see good reviews, you may still doubt it and make further research because good reviews can be bought, but if you see poor reviews, believe it and stay away from the sites with poor reviews. I have found most that are rated poor to actually be bad or scam.
