So i get better coins ?
If i do kyc ? The stable coins like usdt and all ready coins with value ? So i can exchange them instant to fiat if i want ?
No, they're just artificially pegged to USD/EUR.
KYC is not at all related to being able to buy these coins. I'm pretty sure you can get them on Binance just fine.

That might be possible on binance, but it's not an intrinsic property of this coin, obviously.
BTW I'm not sure how it is nowadays, but previously there was no proof at all that these stablecoins were actually 1:1 backed, so just keep that in mind when using them for long-term storage.
