Fixing that is top priority right now. It may take a few days but I'll let you all know once it is done.
I also noticed that when I log in after some time my dark them is all messed up and it is half light and half dark.
Like I said before, many people don't have a clue what they are doing with futures trading so making good tutorial and instructions is must have feature for your website.
I'm afraid we may let you down with our privacy commitments, though. While ideologically we are totally in favor of private transactions, for several reasons we don't want people to use our exchange to mix bitcoins. We may actually do the very opposite and publish all transaction data allowing anyone to link withdraw and deposit transactions, so that in some sense your account is just like a set of public addresses in the blockchain. By doing so we can counter the argument used by governments that exchanges either have to require KYC identification from all users or else they are complicit in money laundering.
I understand that and I don't expect total privacy and private transactions on public blockchain like Bitcoin, but I don't think that publishing all withdraw and deposit transactions will help you with US regulators.
They want strict regulations connected with identity of the person and their documentation, so even some dex exchanges have issues with them.
