Why Coinbase does not support USDT?

Some possible reasons why Coinbase may not support USDT could include regulatory compliance issues, as seen in their decision to suspend USDT trading in Canada due to local regulations. Additionally, Coinbase might have concerns about the stability and transparency of USDT, given the increasing regulatory scrutiny around stablecoins. Furthermore, Coinbase's decision to support only certain types of stablecoins, such as Circle's USDC, which is fully backed by cash and short-dated US treasuries, could also be a factor.
