What about you? Do you regret past purchases?
I don't buy anything with my Bitcoin because I can't spend anything with it. If I did and I was caught doing so, then I could get caught in a country where Bitcoin is not legal tender.
Besides, I still don't have a plan if I'm in a country where spending with Bitcoin is allowed by law, so I probably won't pay with Bitcoin. I don't want to even though Bitcoin is a digital currency.
