Regarding regulation, I believe it would be against the law when the government doesn't legalize bitcoin as a means of payment and someone adopts it in their physical service or company. We know the Indonesian government does not legalize bitcoin or crypto as a means of payment, and if the regulations don't allow it then you shouldn't adopt it.
Of course, the Indonesian government does not legalize bitcoin as legal tender. But you can still own bitcoin, trade them and invest them because it is legal. The legality of bitcoin in Indonesia is still limited to commodity assets, so it cannot be used as a means of payment.
If you don't want to get into trouble with adopting bitcoin as a means of payment in countries where it is not legal, then avoid adopting it. Ultimately adoption cannot be forced, it has to be right.
Actually I also want to adopt bitcoin in business as a means of payment when customers give goods to my business but it is not allowed in my country (Indonesia) so I avoid this and I can only invest bitcoin as a legal commodity and trading tool as an asset.
I avoid that problem because I believe that if forced I will face the law with my business then I will not mess it up no problem I can't adopt bitcoin in business but I can still have assets that are allowed that is also more than enough for i have bitcoin assets.
