In fact, I would choose USDT instead of Bitcoin to pay. The funds exchanges between my friends and I sometimes use wallets to transfer funds. USDT avoids price fluctuations and is more convenient than Bitcoin.
It depends on your location in my country the government has some restrictions on cryptocurrency so the only means of getting any cryptocurrency is through P2P means we don’t use exchange and since Bitcoin is the most popular cryptocurrency, it’s easier to get access to Bitcoin than USDT.
