This is the likely result from this policy change as,
I like to think that cryptocurrency users don’t enjoy it so much when exchanges and the site they operate on are always being subject to stiff regulations. Having to kick out all other stablecoins only to allow USDC? If makes me ask what’s at play here?
What’s the condition for which other stablecoins assets weren’t able to satisfy for which, USDC was able to? It’s just a regulation having to favor indigenous coin and that’s it. Don’t see how they wouldn’t have to comply but, are sure to loss customers in there numbers.
It is conflict of interest among cryptocurrency companies and exchanges. Many months ago, when Binance dominated market shares in cryptocurrency and centralized exchange market, other companies, centralized exchanges turned their swords against Binance. They don't accept BSC chain for deposit and withdrawal for several coins and some even don't accept BSC but they easily accept ERC20 chain.
This action from Coinbase is not strange, like when Binnance launched Binance Smart Chain, they gave free withdrawal fee of BUSD on BSC, but when they felt enough, they began to charge USDT-BEP20 withdrawal fees on users. Coinbase did similarly like Binance did in the past, and firstly it is for their exchange benefit. To get more users from other companies, centralized exchanges, and to force their users using USDC more.
