The problem is, which coin should be merged mined by the miners? I believe there was Namecoin which used the same SHA-256.
Well those who propose spamming the chain with a "new" arbitrary data which they mistakenly call token should create a "new" altcoin that can be merge mined.
You actually posted that?

Ser, I'm here to learn, not to take any sarcasm from people who believe that they are higher than the rest of the BitcoinTalk community. I know I'm a mere pleb, but I merely ask for a respectful discussion on different matters/issues about Bitcoin. If you can't do that, then I'm sorry I'll simply put you in my ignore list.

But apart from that there are a bunch of cryptocurrencies that can be merge mined by bitcoin miners. For example you can see names of some of them in this mining pool's support page with the reward miners can get:
https://support.viabtc.com/hc/en-us/articles/7207416775951-What-is-Merged-MiningThere is also some bitcoin side chains that can be merge mined similarly like RootStock
https://rootstock.io/mine-btc-with-rootstock/Which is another much better idea the "arbitrary data spammers" could pursue instead.

If you were to suggest the best coin that should be merge-mined by the miners, which coin would that be?
