Hey there guys!

I have a long-term wallet that I used to receive donations on, with only 7 receive addresses on it. Today I went on to transfer the funds to a different wallet and found out to have around 31 inputs!
Considering all of them, the final transaction hovered 4600 bytes, which was VERY expensive (around 100 dollars of fee for around 150 satoshi/b)...

Does anyone have a better idea of fee that can be used, as long the transaction doesn't get into the limbo?
I don't really care if it takes even a day, as far the most amount is preserved...

Thanks in advance!
