He wasn't careful enough and he has sent usdt upfront to online seller
Of course he got tricked and seller blocked him instsntly
He's from USA and seller is probably from Asia
What are legal actions he can make and are they in real situation helpful or not?
Thank you
As per your words it look like the transaction was done in usd and not in crypto currency. So you can ask help from the centralized platform on how to deal with such situations. Although i am surprised that you used an online platform and yet there is no escrow implemented to protect the both buyer and the seller. If you don't mind can you share the site which your friend used ?
