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.
I understand that using your bitcoins as a means of payment is prohibited, but you can sell your bitcoins for fiat money on the exchange and spend them, and many of us have probably done this and spent our bitcoins. If you never touch your bitcoins, that's really good. There have been many times in the past when I spent bitcoins, sometimes I can't help but think about them, and sometimes I just say forget it.
The best thing to do is not to think about the bad, make a plan for today and stick to that plan. Because questioning what you did in the past will not bring us anything good.
