Bitcoin jumps another 10 percent in 24 hours to pass $19,000

(credit: NASA) Bitcoin’s price set a new record on Saturday as the virtual currency rose above $19,000 for the first time on the Bitstamp exchange. The gains came just hours after the currency crossed the $18,000 mark. Bitcoin’s value has doubled over the last three weeks, and it’s up more than 20-fold over the last year. Bitcoin’s value keeps rising despite a growing chorus of experts who say the currency value is an unsustainable bubble. One CNBC survey this week found that 80 percent of Wall Street economists and market strategists saw bitcoin’s rise as a bubble, compared to just two percent who said the currency’s value was justified. Another survey  reported by the Wall Street Journal this week found that 51 out of 53 economists surveyed thought bitcoin’s price was an unsustainable bubble. We recently asked two experts on the history of bubbles about bitcoin, and both saw echoes of earlier bubbles in the current bitcoin boom. Read 6 remaining paragraphs | Comments

Code mistake freezes up to $280 million in digital currency

Imagine if one person’s code error deprived you of a pile of money, and there was no guarantee you’d get your funds back. Wouldn’t you be hopping mad? That’s how many cryptocurrency owners are feeling right now. The digital wallet company Parity is warning users that a large volume of Ethereum funds have effectively been frozen after code contributor devops199 claims to have accidentally deleted the library needed to use multi-signature wallets (those that require more than one signature to move funds) created after July 20th. Devops triggered a long-unpatched bug that turned Parity’s wallet contract into a standard multi-signature wallet, making every wallet “suicide” and erase the guiding library code. Whether or not you believe that it was a mistake, it could have very serious consequences. Observers estimate that there could be more than 1 million in ether locked away, which would amount to roughly $280 million. A lower estimate still pegs the damage at over $150 million. Parity describes these figures as “speculative” and suggests you should take them with a grain of salt, but there’s no question that some Ethereum holders are suddenly without a lot of cash. This doesn’t mean that the currency is permanently off-limits, but unfreezing it and compensating users could involve a bailout. And whatever happens, the incident highlights a simple problem: digital wallets and cryptocurrency in general are only as reliable as the code that guides them. The software needs to be airtight if you’re going to tie your livelihood to non-traditional income. Via: Comae (Medium) , Business Insider Source: Parity , Twitter , GitHub

It’s not exactly pulling crumpled cash out your pocket and dropping it off at the bodega counter for a soda now is it? Read more…
