It can even reduce the price of Bitcoin itself.
Hopefully this event will not happen again in the future.
Indeed, I am also hoping that this wouldn't eradicate in the future because this would really bring negative effect to bitcoin price. If US have strong enforcement about those Iranian holders, then I think they had a problem with these people.
There will be possibilities that they have been committing crimes like money laundering or worst is they've been scamming a lots of people.
There's all kinds of drama going on between the US and Iran that this is nothing in comparison. Iran is going through a currency crisis (again) so it's a wonder that they're not all net owners of bitcoin. If I lived there I'd be sure not to hold onto any local currency at whatever cost. Too much chaos.
Lot's of countries are facing similar issues. The Yuan is at almost breaking through 7, which would be crisis level for the Chinese. The Turkish Lira has lost nearly 50% this year. Russia has been facing similar crises. Brazil, Venezuela, I can't even remember the amount of countries anymore. All the reason to be buying bitcoin, but it doesn't seem to be that way.
