Plus many of those projects that have their own "blockchain", and have their own "token" actually DOESN'T NEED neither a blockchain nor a token. They merely mint those tokens, and make up some security/economic model that doesn't actually work like Bitcoin. But they do hope that their users are going to make a presumption that what they're getting is the same as Bitcoin, without questioning the trade-offs.
¯\_(ツ)_/¯
This tokens is the way to pay to their fundrisers
But that STILL doesn't mean that those shitcoin projects needed a token. Plebs should do their research and TRULY understand WHY the Bitcoin network/blockchain needs Bitcoin and study the game-theory in what's making it valuable for all entities involved. It's truly a work of genius, and very well-thought by Satoshi. It's happening as how he envisioned it.
Plus WHEN you understand, you would come to another understanding that shitcoins are not for "investing", they're for gambling.
