I don’t really see anything bad about the website, it just looks like a focused website that only talks about Coinbase and binance.com.  although I would say that they really need to be looking into other exchanges as well, and not just limit themselves to only talking about Coinbase and Binance all the time, they should at least try to include other exchanges and talk about them as well and compare them to these ones.

But, there is nothing bad about the website, they are not asking for money, or asking you for anything at all, they’re just giving their opinion to you and that is it. And another thing you have to know is that they are also not forcing you to take their opinion, no one is forcing you to take any opinion from any website at all. When you get such information, you also need to do extra research and gather what other people has to say about that exchange or whatever it is you're researching on ,before you can make your decision.
