NOTICE: Current bitcoin price increases are attracting many new visitors who do not appreciate that cryptocurrency can go down as well as up in price. Please - do not 'invest' more than you are willing to lose. Thanks for reading and best of luck. 

Note: 'Bitcoin Cash' aka BCASH is a scam - do not buy it thinking that it is Bitcoin.
