The market capitalization is a very bad indicator to judge which cryptocurrency is better or bigger or something else. For example Bitcoin SV was created by fork and automatically 2 billion USD market capitalization was created from nothing

.
So true. If that is not printing money from air, then what is!
More than a half of all cryptocurrencies are practically the same thin air transformed into low quality and low value coins.
By the way I think google searches can represent current interest in certain coin, but it can't give any insight on what coin will succeed in even nearest future.
Having so many low valued/shit coins in the market shows how it is easy to make a token or coin in cryptomarket and to be supported by some investors and some of it managed to survive for so long. We do have too many coins existing today and to be born, Searching in google on what coin will succeed in the future can possibly show you some results, I'm pretty sure that the result showed to you by Google is shilled by some people who are making articles shilling projects or paid review sites.
