Is it halal to sell USDT for GBP

Is it haram to sell usdt for gbp? Can I please have a clear answer on whether this is halal or haram usdt it pegged to the dollar so it should be halal right? But many shayookh including sheikh haitham say it is haram because it is not recognised as a currency by an official government and it has no official backing from a government. Please advise as many use usdt to send money to war torn countries and ect.

Wa alaykum salaam,

My personal view on this is that it is acceptable.

Allah knows best

Barakallah feek sheikh
