That was already a huge number of cryptocurrencies in existence, and Im sure that number will continue to grow because people have never stopped adding projects till today, But I am certain also that most of that numbers are the dead, useless coins/tokens and less than 1 percent has a true demand, use cases, and game-changer functions most of it will eventually die in the process because they have no real use cases no products and services to support and drive the demand of its token so most it will die and abandon.
But when we are the people start ignoring such craps then devs will have no options left other than not creating no more coins and tokens. When we people support blindly by feeding them then definitely this count will grow into 10x or even 100x in coming years and this definitely will have negative impact on the growth of bitcoins.
Because, when people lose money with any scammy token then they may not come back to cryotocurrency space which means bitcoin may lose one true believer. Scams and failed projects will not get investors any good opinion on bitcoin even they have not invested in bitcoins. So, we must take some initiative to stop this non-sense.
