BTC does not have to be a replacement for USD (or your country’s currency)… It just has to be a competitor to keep central banks in check.

Previously, if your central bank printed money, you'd get screwed and have no other option but to use your inflated currency.

But now if your central bank is fiscally irresponsible, you can just switch to BTC.

So even though BTC may be a little slower and doesn't offer offline cash transactions, it still keeps your country's central bank in check.

If your country's central bank is responsible, then BTC price (for your currency) will remain constant. And that's OK!

Either way, it is a win for the people.
