We actually cover all costs for our clients. In regards to the 50%, there are numerous reasons behind this. To name one, any funds held in Xapo's insured enterprise vault aren't instantly retrievable, and we want to ensure our ability to process large withdrawals in a timely and predictable manner.
We're also not saying that we only guarantee the safety of 50% of client bitcoins, we're saying that we only insure 50% of client bitcoins. Safety and security are the backbone of our firm, and any bitcoin company in general.
