A lot of our reserves are held in crypto currency. So it is something to be aware of of, as you would expect. We also hold reserves in several fiat currencies to hedge against any brexit issues with sterling. If the price continued to drop significantly AND we never had anything to push our own coin price up, such as releases or other good stuff, then we would be in a less comfortable position than we would otherwise.
We tend to maintain 6-9months fiat in the bank, but not always, right now we have less than that and would have to liquidate some crypto. It’s not always simple, but something we do keep a tight watch on.
We do not publish every single step though of how we operate and what exact amounts we have in what currency continually as we would only be swamped with well meaning “advice” and there is much more than a simple algebraic equation involved, due to the other aspects of the company/project we do have to consider, some of which would not be beneficial to anyone to make public. Traders will push for headline numbers, but in my opinion it just means we have to spend time stating the obvious.
tl;dr, prices on crypto do affect us as we hold crypto, but we mitigate by keeping various fiat currencies in reserve for periods of instability. This price crash is concerning, but not world ending for us either 
When we liquidate crypto, it is generally BTC as we wish to hold maidsafecoins longer due to the fact we obviously have faith that maidsafecoin can benefit from our work and there is so much more for it to achieve beyond speculative investments.
