There are rumors that Russia are thinking to create its digital bitruble:
According to:
http://cointelegraph.com/news/115302/russia-to-create-bitruble-a-state-run-digital-currency-for-2016:
"The Bank of Russia has begun studies of Bitcoin’s blockchain technology for potential future use. This has led to rumors that Russia has decided to begin work on a new national digital currency, the BitRuble, that will be managed and overseen by the state central banking system, according to late evening reports out of
El Mundo in Spain."
Everyone which understand Spanish can find the article in which is based the above here:
http://www.elmundo.es/economia/2015/09/17/55fb0200268e3e8c708b456e.htmlNot only Russia but even United States are thinking the same thing. According to this article:
https://www.cryptocoinsnews.com/ibm-federal-reserve-want-create-bitcoin-knock-off/"It was only a matter of time. The ultra-advanced, superior technology of the digital currency Bitcoin and it's Blockchain public ledger system are in danger of being co-opted. The tacit compliments of the financial establishment for the Bitcoin Blockchain, not Bitcoin the currency, over the past year are starting to be followed with action. IBM, in conjunction with your centralized banking elite, have discussed plans to perpetuate the future of national currencies, like the U.S. Dollar, through their own digital fiat-currency system."
In this article is even this phrase:
"Keep in mind that only preliminary discussions have been made, and nothing has been finalized. These discussions have taken place with privately-owned Federal Reserve, and other countries may also be potential suitors for this new digitized fiat currency system. The Bank of England may also be very interested in this endeavor, as they lauded the Bitcoin Blockchain in a September 2014 report. The BOE described the blockchain's open ledger as a "significant innovation" that could transform the financial system."
So even England is thinking about the creation of its digital currency.
Are there coins (if created) a risk for bitcoin? Can compete bitcoin with these coins which will be supported by the most important Authorities of every country? Bitcoin have no protectors except their lovers which have not any power except their will to produce, to spread and to use it worldwide. Are them so strong to compete with the Authorities of the above (maybe every) countries (country)?
Bitcoin is ignored by most of the countries and regulated only in few of those. See here for more info about this:
