The issue is BTC is too unstable. The network can send you $3000 in BTC, and you can receive $2800 on the next day due to the coin value drop. However USDT value is fixed, so you avoid the risk and always receive your 3K.Any with Bitcoin payment mode will also do. Provide your Bitcoin address of example Binance and then in Binance, keep converting your Bitcoin to USDT (if you wish).
