Money is primarily independence from one or both of something. Of course a lot of problems can not be solved with money, but most of them if money is solved. You can immediately pay off debts. This is the first thing to do. Invest the money in order to feel confident, too, need.
Personally I will not use bitcoin to pay debts, is my opinion that is better to pay them with fiat and keep your bitcoins at all costs since bitcoin is such a great investment.
Yeah bitcoins should be saved for the future to get higher benefits from it as it price will be much higher in future so its better not to spend them at a moment and keep them for the right time to sell.
