Just a remark, it is a bit bad that withdrawal fees for auto withdrawal are 3000 sats where it used to be free.
Currently bitcoin is very cheap to move with 1sat/byte transaction being confirmed in the next blocks.
Coinpot (online micro wallet) is back to free withdrawals for minimum 10k sat transaction.

That being said, I totally understand that freebitco.in is ad free and their model works better if people leave their funds on the site.
Also, the "slow" withdrawal option cost only 40 satoshi currently, so I would advise not to use auto withdraw for the moment.

Hopefully someday there will be a Lightning option for deposit/withdrawals!
