Stablecoin might be used more, but real value is not good to be held in stable coin, most people see stable coin as a transactional medium, almost like fiat, so they treat stable coins like fiat, but treat Bitcoin as an asset that should be held and not used. Those who only hold bitcoin and not use it may be a bit wrong about their attitude towards bitcoin since it should be used for transactions. But I cannot be sorry for holding my bitcoin for a long term and wanting to preserve value in it, it's my choice. I don't wanna wake up one day and see that my USDT holdings has been frozen in my non-custodial wallet, so I would always transact my USDT in the shortest available time and hold my BTC for the longest possible duration.
Stablecoins offer much needed interface for trading, and for short term liquidity, but they are also plagued by same censorship problems as legacy banking system. Bitcoin, on other hand, provides finality and is immune to third parties.
It is not wrong to see Bitcoin as a Store of Value as opposed to currency, but other logical reaction to its price rise. When an asset is expected to gain in purchasing power, it seems foolish to spend it on frivolous things. This is another instance of Gresham Law, and good money is hoarded. True shift will occur when we can transact in BTC as easily as stablecoins, with help of layer-2 solutions, and without having to give up our long term investment holdings.
