If traditional banking is available to you, then I don't think that there are any significant advantages. But lots of people—notably those in countries with unstable currencies [0]—don't have access to high-quality banking, so for them, stablecoins can be an acceptable substitute in some cases. It's probably not a great idea to hold stablecoins long-term (there's always a risk of the sponsoring company going under, and unlike bonds they don't pay interest), but it should be fairly safe to use them for transfers, since the transfers are quick enough that there are very low odds of the company becoming insolvent while the transfer is underway.

Its a weird loophole or so.

You take 1 $ from someone and give them a token, now you have money the other not. In theory you need to make sure you keep the 1$ but you want to pay people and you are greedy so you invest it and suddenly everyone is broke.

It’s completely unregulated and they can print infinite money.
