it could make sense to spend 0.02 BTC on an iPad Pro, when you know that you spent $4 for the 0.02 BTC back in 2015, and you also know that in a couple of years you could be having a $10,000 tablet in your bag, but at the same time your stash will be worth $10M.
This right here is why the people who say "OMG, deflation would ruing the economy" while they plunder your wealth with inflation are full of shit.
