Bitcoin first comes to existence before tokens or altcoins were introduced, maybe there couldn't have been any of these altcoins and tokens if bitcoin wasn't introduced yet, but it's success birth to other people trying to create something similar to it and that's why they were all been tagged under memecoins and memetokens, they all depends on bitcoin, they are centralized and bitcoin is decentralized.
They uses smart chain contract and other networks other than bitcoin network, their mining is mostly PoS while bitcoin is PoW, if there were no tokens or memecoins, things would have been easier, less scam in cryptocurrency, less or no exchages and the government would have taken bitcoin as their only acceptable alternative digital currency to fiat instead of CBDC.
