It feels like this is a double-edged sword project for them.
If it doesn't work out, they will be left alone with their own network. Cryptocurrency users could still find a new stablecoin to support that uses different networks. I think that's the strength of USDT and USDC, the flexibility of usage in different networks.
If they will continue this, I am not so sure where it will go. So, they are risking a lot here and I do wish they went through deep analysis before they make a big decision.
I can't even imagine USDT and USDC having their own blockchain while obstructing other blockchains from carrying out transactions. This would be the biggest nightmares for these two stablecoins projects that have gotten the heart of so many investors and traders.
This would not last and they could lost investors to other stablecoins that are struggling in the market if the both team choose not to allow other blockchains like BSC, SOL, TON, Eth to stop processing transactions for traders and investors. Let's watch how this would play out when they are done.
