Moon Bitcoin increased payment threshold to 25000 satoshi. The change does not affect withdrawals to Xapo accounts, they remain instant with no minimum.
Due to the massively increased miners fees on the congested bitcoin blockchain, we have regrettably been forced to increase the threshold for automatic weekly payments.
So from 6th March 2017 onwards our policy is that we will pay out on Saturday/Sunday each week providing your balance at that time is at least 25,000 satoshi (this was previously 10,000 satoshi). As before, if you don’t reach the weekly threshold then your balance will be carried forward to next week.
