So I did my first withdrawal via bitcoin to bread. 500 bucks came through an hour ago and it posted in bread as b31,780.20. Ok. I went to transfer this entire amount to Coinbase and it said insufficient funds. So I chose an less easy number of b31,000.00 and that did transfer. When I went back to bread to see the “change” left over, the exact number b780.20 went to a “fee”. I know there are fees but did the wallet assume what I left behind was what I was willing to pay as a fee? It was odd the “fee” was the exact amount I left behind. It was like 7 bucks. Any help on this please?
