Bitcoin passes $7K bringing all 100 top coins up with it

Bitcoin is moving up, and it’s taking 99 of its best friends along for the ride. In the last 24 hours, every one of the top 100 coins by market cap was in the green with 84 of them posting gains of over 5 percent. At the time of writing, Bitcoin was sitting at $7,310, up 14 percent in the last 7 days and up almost 10 percent in the last 24 hours. CoinMarketCap Top 100 Bitcoin itself crossed the $7,000 mark for the first time in the last month, an indication but no sure sign that it might be shaking off a summer slump that’s seen prices plunge below $6,000 on more than one occasion. Bitcoin is quickly moving back toward early June norms around $7,500 though may meet resistance at $7,750. In March, Bitcoin dipped below the $10,000 mark and it’s been unable to mount a rally back above that le...

0x lets any app be the Craigslist of cryptocurrency

Centralized crypto exchanges like Coinbase are easy but expensive because they introduce a middleman. Not-for-profit project 0x allows any developer to quickly build their own decentralized cryptocurrency exchange and decide their own fees. It acts like Craigslist, connecting traders without ever holding the tokens itself. And instead of having to bootstrap their way to enough users trading tokens on their app alone so that there’s liquidity, 0x offers cross-platform liquidity between users on the different projects it powers. The problem is the user experience of decentralized apps is often crappy compared to the consumer apps we’re used to across the rest of tech. From sign-in to recovering accounts to conducting transactions, it’s a lot more complicated than Facebook Login, PayPal, or S...

Kodak-branded KashMiner Bitcoin mining rig for rent wasn’t — and won’t be

Write off another piece of crypto craziness: A Kodak-branded Bitcoin-mining rig that was on show at CES in January, where it generated much headshaking and skepticism that it could ever deliver the claimed returns, has evaporated into the ideas ether from whence it came. The BBC reports that the plan to rent access to Kodak-branded KashMiner devices for the chance to earn Bitcoin returns has collapsed. Spotlite USA, the company that had shown off the rig at CES, was also never officially licensed to use Kodak’s brand for the mining rig, according to the report (although the company does seemingly license Kodak’s brand for use on LED lighting products which nonetheless have nothing at all to do with Bitcoin mining so…). Nor had it installed multiple KashMiner devices at Kodak’s offices, as ...

Russian hackers used bitcoin to fund election interference, so prepare for FUD

The indictment filed today against 12 Russians accused of, among other things, hacking the DNC and undermining Hillary Clinton’s campaign also notes that the alleged hackers paid for their nefarious deeds with bitcoin and other cryptocurrencies. This unsavory application of one of tech’s current darlings will almost certainly be wielded against it by opportunists of all stripes. It is perhaps the most popular and realistic argument against cryptocurrency that it enables anonymous transactions globally and at scale, no exception made for Russian intelligence or ISIS. So the news that a prominent and controversial technology was used to fund state-sponsored cyber attacks will not be passed over by its critics. You can expect bluster on cable news and some sharp words from lawmakers, who will...

Robinhood CEO Baiju Bhatt to talk fintech at Disrupt SF

Robinhood has gone from being a little consumer-facing fintech app to an absolutely giant consumer-facing fintech app. The company, which launched in 2013, has ballooned to a $5.6 billion valuation on the heels of a $363 million Series D financing round led by DST Global. The app has also grown to 5 million users, as of today, with more than $150 billion in transaction volume. But the app, which lets people trade stocks and options for free, is also dabbling in the wondrous world of cryptocurrencies, setting the stage for a potential transition from “fun app” to legitimate financial institution. That’s why we’re absolutely thrilled to have Robinhood co-founder and CEO Baiju Bhatt join us on the Disrupt SF 2018 stage. The key to everything here is that Robinhood offered a simple consumer de...

You can now trade Litecoin and Bitcoin Cash on Robinhood Crypto

Fintech startup Robinhood is expanding its cryptocurrency trading product with two new token listings. Users in selected states can now trade Litecoin and Bitcoin Cash from the app. Robinhood is currently providing one of the easiest ways to get started with cryptocurrencies.

It means that if you buy one bitcoin and if you sell one bitcoin, there wil...

Watch all the interviews from TechCrunch Sessions: Blockchain

What a day. Yesterday, hundreds of people gathered in Zug, Switzerland for TechCrunch Sessions: Blockchain. In addition to some of the key people of the Ethereum Foundation, the team interviewed the entrepreneurs behind Binance, Coinbase, ConsenSys, CryptoKitties and many other organizations. The event was packed with interesting content. But if you couldn’t be there in person, don’t worry as you can watch everything that happened in Zug: Disclosure: I own small amounts of various cryptocurrencies.

RIP “crypto”

RIP “crypto”. You had a good run. This week veteran cryptographer Matt Blaze, finally gave in — to what must have been a near-constant, low-level drone of ‘CAn Buy Crypto.com???$$$$!’ spam — and sold the pithy domain name he registered in 1993, in the midst of the PC era crypto wars, to use as an encryption policy resource, to Monaco, a Zug, Switzerland-based payments and cryptocurrency platform startup whose self-styled mission is “accelerating the world’s transition to cryptocurrency”, positioning itself at the nexus of the current crypto craze. So crypto.com now points to cryptocurrencies. Which seems a fitting moment to say RIP “crypto” as shorthand terminology for an entire domain of cryptographic work that underpins so many more things than just Bitcoin or Ether or Ripple or Litecoin...

Early uses of blockchain will barely be visible, says Hyperledger’s Brian Behlendorf

The blockchain revolution is coming, but you might not see it. That’s the view of Brian Behlendorf, executive director of the Linux Foundation’s Hyperledger Project. Speaking at the TC Sessions: Blockchain event in Zug, Switzerland, Behlendorf explained that much of the innovation that the introduction of blockchains are primed to happen behind this the scenes unbeknownst to most. “For a lot of consumers, you’re not going to realize when the bank or a web form at a government website or when you go to LinkedIn and start seeing green check marks against people’s claims that they attended this university — which are all behind-the-scenes that will likely involve blockchain,” Behlendorf told interviewer John Biggs. “This is a revolution in storage and networking and consumers.” As for where b...

Jina Choi, SF Regional Director of the SEC, is coming to Disrupt to talk ICOs and more

The Securities & Exchange Commission, the federal agency responsible for protecting investors and maintaining fair and orderly functioning of our securities markets, has 11 regional offices, including in Miami, New York, Boston, and Chicago, None has quite the workload as the SEC’s San Francisco regional office, where a major area of focus in recent years has been investor fraud in pre-IPO companies, particularly the many startups that in an earlier era would have either have gone public or else out of business, but which today linger as privately held outfits because there’s so much money sloshing around. Among the companies to find themselves in the SEC’s sights in recent years is HR software outfit Zenefits and its founder, Parker Conrad; they were fined $1 million last October as p...

Korean crypto exchange Bithumb says it lost over $30M following a hack

Just weeks after Korean crypto exchange Coinrail lost $40 million through an alleged hack, another in the crypto-mad country — Bithumb — has claimed hackers made off with over $30 million in cryptocurrency. Coinrail may be one of Korea’s smaller exchanges, but Bithumb is far larger. The exchange is one of the world’s top ten ranked based on trading of Ethereum and Bitcoin Cash, and top for newly-launched EOS, according to data from Coinmarketcap.com. In a now-deleted tweet, Bithumb said today that 35 billion won of tokens — around $31 million — were snatched. It didn’t provide details of the attack, but it did say it will cover any losses for its users. The company has temporarily frozen deposits and trading while it is in the process of “changing our wallet system” following the incident....

Coinbase opens its crypto index fund to accredited U.S. investors

Fresh from revealing plans to add Ethereum Classic to its exchange, crypto giant Coinbase today announced that its cryptocurrency index fund — first revealed in March — is open to investors in the U.S.. The company said in a blog post that it has see “overwhelming” interest from investors, and now it is reaching out to those who want to invest between $250,000 and $20 million. For now, the company said, participation is limited to the U.S. and those who are accredited investors. That’s a pretty big caveat since crypto, by default, is open to anyone — although many ICOs tread carefully in markets like the U.S. — but Coinbase is very specifically target institutional capital, having recently added services for Wall Street-like professional investors. The pitch is that it knows the market, it...
