I've seen those kind of websites many time. Those websites are creating to provide information about those exchanges, probably for them who don't know much and so search details on google about those exchanges! Btw, i like their comparison but they give Coinbase 6.5 out of 10, as well as binance 6.8 out of 10! Don’t understand why rating so low! If they rate such top exchanges like this, then maybe they'll rate 1/2 out of 10 for average exchanges on their next article lol.
I think their assessment is fair, since there is no limit to perfection. Let the exchanges strive to work for quality, then the estimates will be appropriate.
