If you are talking about European countries then in this case USDC will be more popular among people there to use than USDT because since the implementation of
CASPs rules in Europe in 2024, cex have brought limitations in USDT (delisted also).
And maybe that is why people there use USDC in real life?
But this does not explain why USDT is in higher demand than USDC. If the question is about why USDC is in high demand, then this explanation would be useful! Or am I missing something? USDT is banned in the EU by MiCA, so in the EU, people will use MiCA authorized stablecoins only.
I think you didn't understand my explanation well here. I have already mentioned here that the reason why USDC is used more in European countries is the ban on USDT. I didn't mean thats the reason for
I said this here in the context of OgNasty's these words.
I find this curious, as I've found in my personal interactions with people in real life, that USDC is more popular.
What I think is why people on this forum talk more about USDT when it comes to loans. They might be using DEXs or instant no KYC exchanges, and not all of them have the pair that they want, but USDT is universally used by everyone. Maybe that's why. Or another reason can be the nature of the person, because if I am used to USDT since the start, then my first choice is going to be it.
Is this actually a proper explanation? I don't think so,

Because I have already given kindda same explanation, by mentioning the market volume of USDT and USDC. And the higher the volume, the more universally used it is.

And because of USDT is universally used more, that is why USDT is also used in this forum more than USDC, But still, the question here "why USDT is universally used more?"
And here, if I could give a very simple answer in one sentence,
USDT was one of the first solutions that solved this problem so that we wouldn't have to go to the bank again and again for selling Bitcoin.
It started its journey in 2014 and on the other hand,
USDC started its journey in 2018.The thing is that USDT is an adult while USDC is a newborn baby.
