What wipeout? Buyers blew off fresh warnings about a bitcoin bubble and sent prices above $4,800 on Monday, capping a bullish October run for the digital currency.
Prices reached as high as $4,820, which is near the record territory of late August when bitcoin brushed close to $5,000. The currency crashed dramatically in September following a crackdown on digital currency by China.

There is no obvious single explanation for the latest price surge. Possible factors include last week’s rumors that Goldman Sachs plans to trade bitcoin as well as growing confidence that a possible “fork” of the currency in November, which would create a new version of bitcoin, won’t prove disruptive.

We now return you to your regularly scheduled rally. #bitcoin

In any case, not everyone is optimistic about bitcoin’s future. A Harvard economist predicted on Monday that the price of bitcoin will “collapse,” while analysts at TD Ameritrade warned of “collateral damage” to certain stocks if bitcoin prices plunge.
