I heard that banks and the government will start supporting bitcoins which is simply impossible as banks view bitcoin as their competitor and they will never support bitcoins for sure as bitcoin is a major threat to the banking system.
i can not agree with that, i believe that it actually is possible that governments will start adopting the bitcoins if people will leave them no other choicei heard that bitcoin is the currency of thieves and other crime makers though it is used by people who just buy gadgets legally too
So After all bitcoin can be adopted by our government too,
though it will mean that bitcoin will starting to get regulated and taxes
On the other side, Russia is starting to ban bitcoin usage
Where did you get this bs info from about japan. read carefully:
http://www.theguardian.com/technology/2016/feb/25/japan-to-make-bitcoin-legal-currency
"Japans governing Liberal Democratic party is planning to propose legal changes that would define bitcoin and other cryptocurrencies as currencies."
So for now the party just PLANS to propose changes to recognized bitcoin AND OTHER cryptocurrencies as currencies. It says nothing about their national currency. And if this would heppen:
"The changes would mean bitcoin could be more tightly regulated and taxed"
Not sure this is what bitcoiners really want more regulation and taxes on their cryptocurrencies.
