When it comes to practical daily usage, then the answer is "YES", Stable coin, most especially USDT can out perform Bitcoin when it comes to practical daily usage. Because when it comes to Bitcoin, the majority of people who invest in it, does so because they see it as an asset for long term investment. And not an asset for daily transactions usage due to its volatile nature, fluctuating up and down due to demand and supply. But when it comes to the overall cumulative total volume invested, Bitcoin will still always has the highest percentage, simply because most people believe in Bitcoin more than they believe in other Altcoin.
There was a time when exchanges list coin, they pair it with usdt, usdc, Bitcoin, Ether and probably the exchange coin to boost liquidity but now, it's all around stable coins, this has reduced the exposure of trades between Bitcoin and other coins that's why volume of Bitcoin traded has reduced and why stable coins has had a massive increases but it doesn't change the fact that people use Bitcoin everyday, if not for volatility I'm not sure some people would consider having stable coin on their side.
I have seen posts many times about millions lock on stable smart contracts but I can't remember any post where anyone mention Bitcoin were seize, the more people play around with stable coins, more of them will be sieze and people will know the difference between the them. Some people are using stable coins because they don't know it, even the ones keeping coins on the exchanges don't listen until they become a victim one day and they turn super angelic on why stable coins should be avoided.
