Listen, mate, I am going to give you fair advice that there is a reason that Google only shows top 10 of 15 websites. Most of the websites on the internet are full of scammers. They just try to take your money by letting you into their fake website. I know that not all the website on the internet are fake, but it is hard to distinguish between a fake website and a real one so jumping into a Very respected website is much better than going on the professional website maybe that is not fake but still it's better to take precautions then treatment. So I will advise you can visit
coinmarketcap which has decent website information about any altcoin or Bitcoin you are searching for.
I certainly agree with you. Not everything that we search result and everything we read in google are legit. Even reviews are also fake most of the time. Some scam sites are faking reviews so we have to get rid of them.
If you're looking for an exchange site to use, better choose a well established and trusted with a high reputation so that you'll not regret risking your funds in the future.
