USDT And privacy?

i very much care about the KYC.
tough i tought localmonero/agoradesk are just for monero/bitcoin.

anyhow like i said in the original post i hard that kucoin do not require KYC Up untill to a transaction equal to 1 bitocoin?

another question: is the wallet i would use depends needs to change depends on the chain i took for the USDT? if so what wallet can you reccomend for the OMNI chain?

Final question: what reason do you have not to trust stable coin?
