There is currently a network attack on BTG! Please do not withdraw or deposit funds until the attack is over.
The attack is reported on miningpoolhub: "- Bitcoin Gold network is under attack. As there's many orphan blocks generated, profit may decrease temporarily."
I have personally been affected by the attack, my funds are being held up (for over 8 hours now with 0 confirmations) and I don't know if I will get them back!
