> Presumably, displaying a bitcoin address isn't illegal, and you are not in control of who sends you coins.
Both parts of your statement are naive and wrong.
Soliciting payment in any currency other than the national currency is illegal. No one is going to be fooled by claims of "oh I just put our corporate bitcoin address up for...uh...personal aesthetics; we weren't actually suggesting customers can pay us that way".
In any case, where is the documentation for the annual audit? When the tax department looks at the corporate bank statements, what do you think they'll see?
I own a company here, we are required by law to hire an external auditing agency. Do you think the auditing agency is going to, what?, just lie to the government for me when it is obvious to them I'm accepting payments in bitcoin since there is no documentation for local currency payments?
The tax departments come to our office every year and goes over the books. They are looking for tax evasion, money laundering, and so on. But it would be pretty trivial to spot if someone is getting paid in Bitcoin.
I'm trying to imagine how you think the conversation would go when they audit the company Bitcoin account, "Oh, gee, some bitcoin got transferred to the company account. Dunno how THAT happened! Ha ha. Guess it was just a DONATION! We were definitely NOT breaking the law! Don't look at our invoicing system that shows we marked that as a payment received for order #81351."
Just like nobody can _stop_ you from murdering another person or demanding a bribe or any number of terrible things.
I don't understand the point of your vehement sophistry. Everyone understands how societies work. There are laws. People get punished after the fact for transgressing them. Cryptocurrency is not somehow magically exempt from that reality.
The person you replied to said that cryptocurrencies are illegal where they are. You said nobody can stop you from accepting cryptocurrencies. Just like nobody can stop you from doing any other illegal thing, like not paying your taxes or taking drugs. Sure, you can do these things and you may even get away with it, but if you get caught, you get fines or jail time or whatnot. If cryptocurrencies are illegal where the person you responded to is, sure they technically can accept cryptocurrencies, but if they get caught, its no different than getting caught doing any other illegal activity. You might say "well, its hard to get caught!" but you could say the same thing about laundering money, evading taxes or buying drugs, yet people get caught doing these things all the time.
