How likely do YOU think this scenario is? Although you might say this is only speculation, IT IS A FACT that these countries are working on cryptocurrencies of their own.
Ok I think we have debated on this issue severally and have come to a conclusion that it doesn't really matter what they (the government) come up with because they'll fail woefully. They tried previously to create fud and cause panic among the investors and discouraged them form investing in the technology therefore bringing the coin down to it doom but all their attempts were in vain since it only had a short term effects on the may.
The government are secretly buying bitcoin just as the institutional investors were hiding before they made their holding public. The government know the technology is above their reach for all their selfish tricks. Don't be surprised if to know they must have go through all their books just to find something worthy of discredting the currency but all they can come up with is, 'it encourage criminal activities' meanwhile their fiats scams has been doing that for years now
There's a high possibility of the government finally joining the party instead of fighting it, knowing they are on the losing side already. Just my thoughts though.
