Bitcoin is an open network – meaning users can send and receive bitcoins on the network using bitcoin wallet software. Anyone can run bitcoin software to become a bitcoin node or a bitcoin miner as long as they play by the bitcoin protocol rules.

Abra is a bitcoin-based digital wallet app that lives on your smartphone. It is the easiest way to buy, sell, store, send and receive bitcoin from anywhere in the world. It’s similar to a brokerage, but it’s also a wallet. Abra supports bitcoin as well as over 50 global currencies which means you can convert in and out of bitcoin or any available currency, easily. You can also send bitcoin to anyone who has a bitcoin or an Abra wallet and receive bitcoin or money.

Digital gold: why hackers love Bitcoin
In the earliest days of ransomware attacks, which often gain initial entry to a system via an innocuous-looking email containing a link that, when clicked, offers a hacker access to a network, payment methods were limited. “The odd hacker here or there could deliver a message to send money via Western Union or to a bank account, but that transfer was always traceable once the authorities were involved

Then came Bitcoin, a virtual or cryptocurrency invented by Satoshi Nakamoto, the alias for an anonymous programmer or collective, and launched in 2009. It offers two major advantages for cybercriminals: by operating as a decentralised currency, in which people pay each other without a middleman (like a bank or credit card company), it provides a lot of anonymity.

Despite the initial alarm he observed in 2009, Moore is similarly optimistic about the power of Bitcoin to change lives, and believes its momentum is irresistible. “You and I are probably unrepresentative of so many people in the world who may not have access to bank accounts and credit cards,” he says. “There will always be millions of people who need ways to transact outside the immediate control of large institutions.” Closer to home, he says his own daughter, who has just started working for a cybersecurity company, is ineligible for a credit card. “For her generation, bitcoin is something attractive.” His only regret about bitcoin is that he didn’t buy any in 2009. Six hundred dollars bought even as late as 2011, when the bitcoin achieved parity with the US dollar, would today be worth a million dollars.

More than 10% of $3.7bn raised in ICOs has been stolen: Ernst & Young
Anna Irrera:
<p>More than 10% of funds raised through “initial coin offerings” are lost or stolen in hacker attacks, according to new research by Ernst & Young that delves into the risks of investing in cryptocurrency projects online.

The professional services firm analyzed more than 372 ICOs, in which new digital currencies are distributed to buyers, and found that roughly $400m of the total $3.7bn funds raised to date had been stolen, according to research published on Monday.

Phishing was the most widely used hacking technique for ICOs, with hackers stealing up to $1.5m in ICO proceeds per month, according to the report.

The research also noted that the volume of ICOs has been slowing since late 2017. Less than 25% of ICOs reached their target in November, compared with 90% in June.

The study comes amid a cryptocurrency investing craze, with young companies raising hundreds of millions of dollars online to fund their projects, with often little more than a handful of employees and a business plan outlined in a so-called “white paper”.</p>

Going to keep pointing this stuff out until the inevitable happens.
