Bitcoin is and will go down as the greatest ponzi scheme in history...backed by nothing it is nothing....and nothing is what it is and what it seems.....the mysterious Satoshi...hmm...? Some Say the dollar and others currencies are nothing except they are backed by govt backed by a military...that's not nothing....bitcoin is a speculation its useless for trading....valued in other currencies is the real tell....even try and turn it into fiat(other currencies) and the exchanges take a massive chunk...it;s unregulated.....40 % percent of it is owned by less than a thousand people...and the price rises ? why ? cos theyre selling it back and forth to each other...it's the old trick in the book...illegal on a regulated exchange...but wait it's not regulated .....got in early good luck to you...get out early....too late stay away
