many shitcoins are still appearing so I doubt that early shitcoins will attract some kind of interest. and there are no rare shitcoins because they all can be found on ETH blockchain.
To find Shitcoin is very easy because it is not only on the ETH Blockchain, but on the BSC Blockchain and other Blockchains as well, because Shitcoin was born by irresponsible people whose only goal is to take investors' money.
