I feel very bad if something like that happens on Bitcoin blockchain. The stable-coins have no place on Bitcoin blockchain and if someone adds those into it just like ordinals then that might be a problematic issue for the Bitcoin users. The stable-coins are okay in their current state and adding them on Bitcoin blockchain will be an extra burden on Blockchain.

I will never use such useless stable-coins that can cause network congestion in Bitcoin blockchain. They have no use on the blockchain but there are those people who create such projects to disrupt the working state of the Bitcoin. They won't be successful in their operations because the developers are already trying to find a way to stop the Ordinals protocol.

Those useless stable-coins will affect the sate of Bitcoin without any doubt, they will cause huge congestions to the market and because of that the fee could go very high once again after that BRC-20 tokens. Although, I'm not against such project but due to limited block size of Bitcoin blockchain it isn't worth to add those things in the blockchain.
