agreed, the ratings are good for nothing. These websites make money from paying ICO's for their ratings, they are a ton of good examples why not to trust them.
For example project " Titanium" had good ratings everywhere, they where  scam in the end.

At the moment, the most respected rating agencies with the most extensive databases are ICOrating and ICObench. They have been on the market for quite a long time and their ratings have proved to be fairly objective and therefore worthy of attention.

Bitcoin's growth began in early 2017 and then it touch 20000. Bitcoin's largest growth is due to the ability to trade with tether dollar. With this growth, a huge growth in ICOs appeared. Nowadays about 30 ICOs are added to the market. This huge volume of ICOs, has taken the power of bitcoin growth. Like weeds next to a tree. Bitcoin will not grow until ICOs exists.

Found an interesting article in which one guy did some datamining on some popular exchanges and their volumes:

Apparently a few of these giants are falsifying their volumes. Maybe because a higher market cap would make people think it's a more trustworthy exchange? I don't know if it's really worth going through all of that effort.

Would this have a major effect on the prices? I know we used to see huge differences in prices in the past, but now you won't see much more than a few percent here and there between exchanges.
