This thread is from a few years ago, but it still validates the idea that with each passing day more projects are being launched and the trend is to increase even more, since each one believes they have the right idea, they will certainly try to make it a reality. Whether there is any use in these projects is another story, the BTC itself struggles to be useful to people, let alone other projects, ETH and some blockchain projects serve as a bridge to other projects, but what about the others?
Come back and check this topic in 5 years and you will be shocked. There will be even more and more coins created every single day, look at coinmarketcap and you will see that there are nearly a coin a day and probably more in most other days, and that is just coinmarketcap and I know a ton of other coins and tokens that did not get listed in coinmarketcap neither. At the end of the day if you are not listed at all that means you are not checked at all neither so I remove all of that, but even still with that cmc has so many coins, even while delisting some of them.
Long story short there will be more and more coins every year, there will be at least a thousand coins where over a thousand people invested every single year, in 5 years that means over 5 thousand projects with a million joined (overlap of course, one person can join multiple) so that is never good for us in financial sense. However this allows improvements and show us all the new stuff so that's good.
