Do I get that right, you plan to spend
BTC for something just for the sake of spending
BTC and plan to later buy it back?
Can't follow this line of thought to be honest. Spending
BTC is not fun, it's always painful as you sold always too early. Buying
BTC is the fun part.
Again (mis-)quoting JimboToronto with: "Buy if you can, sell if you have to."
