Op, this is why businesses are skeptical of accepting bitcoin. The volatility factor doesn't make it favourable to use bitcoin in business. Think of it, apart from the volatility, how about the transaction fees? In some business transactions, the transaction fees are way higher than the profits, especially when the mempool is somehow congested and transaction fees skyrocket.
If there are regulations, it will be easy, but if some still prohibit it, it will be a bit difficult. But I think that time will come sooner or later, and it will become a reality, not just the items you mentioned, but much more. Yes, BTC offers a digital financial solution for the future.
If it's not legal and bitcoin is being used to conduct a transaction in that country and the seller is not someone who can just take transactions for what they are, then we might likely see a case like the one that happened in 2023, where a man bought a luxury car from a lady and paid with bitcoin because the value of the coin had dropped below what they initially agreed for the car, and he was sent to 18 months in prison.
Hmmm... Many things happen in this space. I am not aware of this. Why was the person jailed. Was it because of the volatility or because bitcoin wasn't official as a means if payment in the country?
