Yes, that's definitely insane, but it's also not new. I remember back to 2016 and 2017, when it was even worse. There were 20-30 new ICO projects every day. One lost the overview. And a similar number of projects were listed on Coinmarketcap every day at that time. Then, during the years of the bear market (2018-2020), there were significantly fewer new projects founded. With the bull market and the NFT boom, this then changed again.
Also interesting is an article from Techcrunch from 2017 about which projects are promising. You only have to look at how many of them are still in the top 10 at CMC and you get a good impression of how fast-moving crypto is.
