This list is something I totally recognize all the cryptos, but if you look at Coingecko updates you will see that the weekly searches are based on a lot of unknown cryptos, it's weird.
Bitcoin will be always searched as the indicator of the cryptocurrencies prices. As for the rest of altcoins, new tokens will be “Googled” for often than others, when they become hype projects. This statistics will be always flexible as everything on the crypto market.
