Many people still believe that Bitcoin can replace Fiat but I don't see it happening, it's not because of banks or this centralised world either.
Bitcoin will never replace fiat, fiat remains the main means of payment.
The government will not let fiat become extinct.
Do you also accept BTC payment? What's the experience between a bear BTC market and a bull BTC market?
I don't have a shop... even if I did, I wouldn't be able to accept BTC payments because of regulations that prohibit it.
I have purchased goods abroad and paid with bitcoin and there is no difference between the market being sluggish or rising, it's the same as buying with the equivalent USD at that time.
