As we can see, bitcoin’s fees are significantly higher compared to other currencies, which is why the OP pointed out that it feels like a wrong move. If you think about it, saving even a small difference in sats by using other currencies can add up over time, especially during a bull market. It makes a big difference, especially if you value your money. But if you are a wealthy person, then sure, it doesn’t matter.
The main reason most gamblers prefer using stablecoins is #1: transaction fees. They choose what saves them the most money instead of spending unnecessarily.
Some altcoins, like ethereum for example, have extremely large fees, but people still use them.
The thing is that we are now in a transition stage, whereas you still can transfer Bitcoin directly on-chain and in a second layer, with lightning.
It will take some time, but eventually on-change movements will be done only for large amounts of money, and lightning or similar will be used for daily transactions.
It's like the money in your wallet when you go out, you don't carry all your life savings all the time, you just have a small amount ready to transact.
