Each time you want to drop another comment and there is no gap between your previous comment and another member's own, you can just edit your post and add it together. I reported your first mistake and the moderator has merged it together.
My friend has recognized that he is at fault, it was on his end. He is going to send me another $1,000 USD in btc, this time, we will check things carefully.
It’s good that your friend has agreed to send back the money and taken the fall for his mistake instead of shifting blame… this is indeed a very big loss for your friend and I feel for him.
