Hedging is actually not idiotic at all. It is in fact what most large organizations do if they have currency or interest rate risks with respect to their accounts payable. That's why the OTC derivative market is so huge. It is certainly not 'idiotic' to think about it and have a plan for it given how volatile BTC is. Let me give you an example. Let say BTC reaches $1000 in 3 months and then crashes to $200 in month 4. Lets say the Board plans to spend X amount of BTC or USD in the next 12 months. That X amount is being spent regardless in the next 12 months. It is not being held long term as an investment - so one's view on the long term future of BTC is irrelevant. Hedging would mean the Foundation would have sufficient funds available regardless of any crash in the price of BTC. Again, we are spending a certain % of the funds regardless, not holding it all as a long term investment.
You dont hedge as a trading strategy you hedge to make your balance sheet deterministic.
