What exactly is the available balance?
Your available balance will be displayed on the overview page of your bitcoin.de account and represents the credit that you have at your disposal currently.
For example: if under "Reserved Balance" an amount of 1 Bitcoin is shown, but under "Available Balance only 0.5 bitcoin are visible, it may be that the other 0.5 Bitcoin have been blocked by our escrow, because you have published an offer to sell 0.5 bitcoin on the marketplace.
