It is a hugely ambitious - some might say megalomaniacal - project to create a new global currency. Facebook's David Marcus tells me it is about giving billions of people more freedom with money and "righting the many wrongs of the present system".

Bitcoin and the blockchain may seem like puzzling new technological concepts, but the central tenet of this cutting-edge cryptocurrency goes back way longer than you might believe.

In what is either an incredible blockchain-enabled monetization opportunity or a sign that perhaps the gears are finally starting to fall out of this thing, Republican politician, failed presidential candidate, and former Pennsylvania Senator Rick Santorum is a cryptocurrency guy now.

18 minutes is all that it takes to understand Bitcoin better than most people. In 18 minutes, you will have a good understanding of how hash functions, Public Key Cryptography and Merkle Trees are brilliantly used in Bitcoin. The purpose of this post is to provide a semi-technical guide to key aspects of Bitcoin’s technology.

Coinoimi cried extortion when a user alleged the crypto wallet provider cost him $70,000. Now, it has published a new report by cyber-sleuths CipherBlade. But maybe Google has the answer.

In an interview for Bloomberg Jon Erlichman asks famous billionaire entrepreneur, Tim Draper, about bitcoin. Despite its powerful technology, people are more interested to hear about bitcoin from the investing side, about the price where is going to be in the future.

Bitcoin mining difficulty has now reached its all-time high, crossing 7.46T for the first time and narrowly edging out the 7.45T difficulty seen when Bitcoin was testing the $6,400 support levels in October 2018. The fact that both Bitcoin (BTC) prices and mining difficulty have soared in the past several months indicates that confidence in the digital currency is growing...

Investing in Bitcoin comes with a huge element of risk. Infact, investing in anything is risky as generally speaking, you can never guarantee a positive return on that investment, no matter what you’re buying.

Two bitcoin cash (BCH) mining pools recently carried out what is known as a 51 percent attack on the blockchain in an apparent effort to reverse another miner’s transactions. The move is tied to the bitcoin cash network hard fork that occurred on May 15. The two mining pools — BTC.com and BTC.top — carried out the move in order to stop the unknown miner from taking coins that they weren’t supposed to have access to in the wake of the code change.

We went a long way since the first time two people decided to exchange goods. At the dawn of civilisation, barter was the only peaceful…

2018 and part of 2019 was called "the crypto winter" by many due to huge losses. Bitcoin tumbled from its all-time-high of nearly $20K during December 2017 to $3400 in roughly a year. This massive market reversal caused many newcomers to the cryptocurrency space at a loss. These losses have caused a lot of anguish and personal issues to investors and individuals. Many have reported massive losses while expecting gains. It appears that it may have even broken up a marriage or 2.

Investors have returned to something of a selling mood from the Memorial Day holiday, which also — hurrah — marks the unofficial start to summer. That’s as trade tensions remained static following fresh comments from President Donald Trump which appeared to offer just mild encouragement over the China spat. From Japan, he said he expects a deal “sometime in the future.” That’s pretty vague for financial markets, which will increasingly hang hopes for a deal on a G-20 meeting in June, where Trump and China President Xi Jinping are expected to get together.

Added to numerous hacks and scams damaging the cryptoverse are the fraudulent practices of Estonia-based bitcoin trading platform, Paxful Inc. Recently, after listening excessive complaints against Paxful Inc., United Global Resolve for Peace (UGRP) petitioned the illicit nature of practices by Paxful Inc. to the Economic and Financial Crimes Commission.

The larger lesson of an ongoing Ethereum crime spree: Be careful about who's generating your cryptocurrency keys.

Although the stock market may have hit a new all-time high recently, investors are feeling increasingly worried. According to one metric, fear is at its highest level in roughly 50 years. Will investors flock to alternative assets — like Bitcoin (BTC) — as a result? For many older investors, the 1987 stock market crash is like recounting a period in Hell. The crash then was the biggest single-day wipeout in history. Worst of all, it came after unprecedented growth — much like today. According to the Leuthold Group, some of the current stock market trends seem to point that we may be soon experiencing a repeat of that dark day.

On May 06, 2019, renowned Bitcoin Core developer Peter Wuille announced two new Bitcoin improvement proposals (BIPs) which are aimed at improving the privacy of the blockchain. Peter Wuille submitted two new proposals, both for a new taproot softfork which will overhaul Bitcoin's privacy, by describing a new transaction output type known as a 'SegWit version 1 output type.' In the BIP, Wuille provides a thorough technical overview of the proposal and argues the rationale behind the plan.

According to information presented on Messari.io’s OnChainFx rankings, Bitcoin accounted for nearly $580 thousand USD in fees in the last 24 hours. On May 10, 2019, at 9:50 am UTC, Bitcoin miners earned more than eight times the transaction fees than the combined total of all other cryptocurrencies listed on the site.

New risk rules for cryptocurrency exchanges will be put to the test with the latest hack on Japanese exchange Coincheck. Hackers stole US$660 million worth of NEM (its native cryptocurrency). In the past eight years, more than a third of all cryptocurrency exchanges have been hacked. The total losses exceed US$1 billion. Because cryptocurrencies are almost untraceable, the rate of recovery after a hack is very low.

Nearly 95% of all reported trading in bitcoin is artificially created by unregulated exchanges, a new study concludes, raising fresh doubts about the nascent market following a steep decline in prices over the past year.

On March 28, 2019, the Bitcoin (BTC) blockchain recorded a total of 393,698 confirmed transactions as both its hash rate and coin price climbed steadily over the past month. Confirmed transactions are now at the highest value since the beginning of January 2018 and are just 20 percent lower than the highest ever recorded value of 490,644 transactions per day achieved at the absolute height of the 2017 bull run — indicating that interest is picking up for the dominant cryptocurrency.

Julian Assange, who had been living at the Ecuadorian embassy in London for seven years, was arrested Thursday morning after the country’s president rescinded the WikiLeaks founder’s asylum status. Assange’s eviction has caused an uproar across the globe. WikiLeaks editor-in-chief Kristinn Hrafnsson and Edward Snowden both said the arrest marks a “dark day” for press freedom.

Xapo CEO and director at PayPal, Wences Casares, recently made some spectacular claims about the potential price of Bitcoin in the future in an essay that was published in Kana and Katana, stating: “In my (subjective) opinion those chances of succeeding are at least 50%. If Bitcoin does succeed, 1 Bitcoin may be worth more than $1 million in 7 to 10 years. That is 250 times what it is worth today (at the time of writing the price of Bitcoin is ~ $4,000).”

The volatility of bitcoin price has surged nearly 200 percent from a monthly low of 1.26 percent to 3.31 between April 1 and April 2, according to Bitvol.info. Currently, the volatility stands at 3.54 percent.

When you talk to tech industry insiders about where Bitcoin is heading, two vastly different comparisons are inevitable: the tulip bulb and the internet. Bitcoin’s critics say the digital tokens are like the tulip bulbs of 17th-century Holland. They generated a wild, speculative rush that quickly disappeared, leaving behind nothing but pretty flowers and wrecked bank accounts.

Today, with the assistance of Bitcoin, you’ll revolutionize the means you are doing your business. you’ll create payments with virtual currency anytime in an exceedingly matter of many seconds. And you will not need to pay something to associate mediator as there’ll be no card process concerned. You have your Bitcoins in your own Bitcoin notecase, which is able to form of your own bank. however there’s a catch. If you lose your notecase key, you’ll now not have access to your digital cash.

Japanese startup Nayuta is releasing an in-progress lightning implementation with a compelling new focus: the internet of things (IoT). As revealed exclusively to CoinDesk, Nayuta is publishing the first lightning implementation geared specifically toward IoT, or networks of connected devices that feed data to one another. The idea behind Nayuta’s release is that it connects to bitcoin’s live network (as opposed to a test one), allowing transactions of real BTC.

Rakuten is considered the Amazon of Japan - like Amazon they started in the 1990's and have grown to dominate their countries online retail sales to become the #1 e-commerce site in Japan and among the world's largest by sales. They've just announced their plans to launch a new cryptocurrency exchange, Rakuten Wallet, along with plans to make using and spending cryptocurrency easier for the average Japanese consumer.

Cryptocurrency exit scammers and exchange hackers have made a killing this year, and soon they'll have to launder it all...

Remember bitcoin? It's back. In a big way. Bitcoin prices have surged nearly 60% to about $6,000 after plunging almost 75% in 2018. Sure, the cryptocurrency is still far from its all-time highs of just under $20,000, which it hit in December 2017. But crypto investors are increasingly optimistic that the bitcoin (XBT) bounce of 2019 is real and that it and other cryptocurrencies may enjoy a steady march higher

At the back end of April, the New York Attorney General (NYAG) accused Bitfinex and Tether (USDT) of covering losses of up to $850 million. The revelation was the latest salvo in the long-running Tether/Bitfinex controversy. When the news broke out, BTC dipped slightly as Bitfinex users understandably dumped USDT. In the past, a story like this would have had a catastrophic impact on Bitcoin’s positive market sentiment.

Bitcoin has had a good run in 2019 as it is currently approaching the $7,000 mark. This, after the bitcoin price dropped as low as $3,200 in December 2018. Although it might still be too early to think that we’ve entered a bull market, there are some financial advisory firms and Wall Street veterans who’ve made some very bold Bitcoin price predictions.

While stocks are showing considerable volatility as the U.S. and China begin rattling their trade sabers again, cryptocurrencies are getting a second life with investors. The Dow Jones Industrial Average has oscillated up and down for the past five days, ultimately losing roughly 1,000 points. On Monday, as China announced plans to raise tariffs on $60 billion worth of U.S. goods, the Dow was down a whopping 562 points, as of 10:55am ET.

This year is quite the opposite of 2018 in the cryptocurrency ecosystem. While last year was dominated by adverse reports about cryptocurrencies and how they were plunging in value, this year has primarily experienced massive comebacks. In particular, Bitcoin has led a significant rally since early April, and it seems not to be ending any time soon.

Bitcoin was barely a year old and trading for less than a penny. Excitement for the world’s first cryptocurrency was still largely bottled up in the infant hobbyist forum Bitcointalk, itself barely half a year old. Here, OGs effervescent with enthusiasm compared notes on economic philosophy, technical knowledge and the new cryptographic beast that Satoshi Nakamoto created. Satoshi himself was still active on the forum, too, as the earliest adopters shared their visions for the future of money.
