Hi Bitsane,
on 2018-01-11 I withdrawaled 1.29 ETH where the transaction failed. The support ticket hadn't been replied since now! TxHash is 0x1d8abe11659cab3cb51f5901e9054aff94462f3cbb25b1b2216ae878aa129a96.
The transaction failed because of low gas limit of 21000. I don't understand why the transaction had been created with such a low gas limit.
Earlier the day I made a similar withdrawal, where the gas limit had been 33705 - TxHash 0xc295326a894ee2a399fb5c3d12e78b5ab6ebb16237144069b982ab08dcdcf140.
Please get someone on this issue and either start responding to opened tickets or create at least a status page where you inform users about platform status.
Best regards
EDIT: fixed date of withdrawal
