If the dollar is worthless, we can compare Bitcoin with gold, oil, gas, rice, burger, cigarette, sake, iPhones, Netflix, and other goods. So, I don't worry about it.

I don't know why people out there always compare Bitcoin with the dollar?, I don't know why it's necessary because our local exchange didn't use dollars but Rupiah. So if the dollar is worthless, I will compare it rupiah to buy goods, or if all fiat is useless, I will go to Elsavador to buy a burger. Simple.

don't worry, we wouldn't die without dollars.
