>Why do they have to be careful? Are they going to magically going to have to start accepting Bitcoin instead of dollars? There is zero chance bitcoin with it's current network is every going to be used as money. What might happen however is that more and more transactions could move towards other networks like nano or various stablecoins that are built on top of smart contract platforms. If governments end up issuing a currency that is only useful for tax payments then they have effectively lost control of the monetary policy. And in any case banning crypto will only help towards redirecting monetary flow towards other countries. So in many ways governments' hands are tied in this.
