Bitcoin is improving the countries financial statements, by giving some money to the unemployed people. Btc wasn't directly impact on country stability, only indirectly help the usual people
That becomes a direct relation in other words. Like if a person was once unemployed and he was taking money from government for his living. Now, bitcoins have helped him to earn some money from signature campaigns or anything else, he is getting to be wealthier day by day. So he will be starting paying taxes and the ultimate help will be made from this person to the government, hence increase stability at individual level.
That's why some country finds way to bans it or still studying it on how they can benefit from it besides the taxing when converted in fiat, they knew that when the holders investors just decide to cash it out that will be the only time they can be taxed them, and know how smart some investors are they might not cash it out in their country or use anywhere else, So government need to supports it in aproper way starting to a individual , to their community to their country , so we can see how crypto will help as long as the government supports it.
