Yes, as we know, Bitcoin appeared in 2009, and over 9 years of its operation( trade)... that the authorities would pay less attention, legalized in mainly Japan...as time went on... who row on bitcoin earned a lot of money...many did not believe this... and here are scammers - hackers quickly figured out how to "earn" this currency...and that's when 17 Dec 2017 he stood up to the mark 19500...it is here that he surprised everyone!!!...once all stirred, bitcoin stirred the whole World! Where was all this before? Why the authorities of all countries are not created during its own laws, its own rules of operation with cryptocurrency?...and because many think that bitcoin is a "Scam", bubble, pyramid...so it is easier to say than to understand, to learn, to understand...It's a new technology now blockchain and bitcoin - it's the 2nd aspect of the same system!!!... And therefore, when authorities in their fields realized that many in bitcoin got rich...started to apply its own laws...the first came from China and South Korea...and 17января bitcoin fell to a label 9148...this is thanks to an experienced, large , professional investors it does not fall below 9000...and after 17 January he is above the mark 13000 was raised, because he is waiting for authorities what they decide...of course they have now begun their work...The Finance Ministry published a bill on bitcoin...and other countries have their own rules...but nerves do not iron at all , you need- to settle in a single position regarding cryptocurrencies...Of course, after all the turmoil and razberi we expect the GROWTH of BITCOIN!!! GOOD LUCK TO ALL!!!
