coin selection code does very badly in some cases #1643
He was trying to send 0.0011 BTC, and was charged 0.0445 in fees. That's a 4045% charge. According to the user, there were "a lot of better fitting inputs".
The coin selection code doesn't attempt to minimise fees. Perhaps it should.
The transaction spent the following outputs:
571 single satoshis, plus these 15 amounts which sum to 0.05559429:
0.00007550 0.00009679 0.00011887 0.00014177 0.00019014
If just the last of those 15 was used, the fee would have been either 0.0005 or 0.
