Due to the free access to the source code and because of the ability of everyone to create their own cryptocurrency, a significant part of altcoins is useless or even fraudulent.
Exactly, currently token creation is very easy. I found several token generators on various networks. They only need to pay a certain number of coins to generate tokens. For example for BEP20
With standard tokens, i only need to pay 0.5 BNB. After that, I can do a sales for each wit 0.01 BNB, its mean I only need 50 tokens to get back my creation fees. After I can do a sale for 8000 tokens, i get a lot of money, and can run with that.
Thats why, we can see new tokens everyday and rugged, because for me, I just need to create a concept, and if looks good, maybe I can sell my tokens, even I'm not a programmer can create it.
From here, we can learn something, always careful when every new crypto enthusiast buying any new altcoins. Because new tokens is easy to dead or rugged.
