Revenues for Bitcoin miners dropped to their lowest point in 19 months this past February, a 10% month-over-month decrease since 2019 began. The good news: gross margins, which reached their nadir of 32% in January 2019, grew to 39% in February. Meanwhile, hashrate has been growing since December 2018. Talk of a miner death spiral may have been overblown; Bitmain's newest miner, the S15, has sold out twice over, with a new batch planned for April.
Bitcoin Hash Rate, Miner Margins Shift Back into Growth
"Bitcoin miner revenues last month fell to the lowest intake since August 2017. To make matters slightly more difficult, miners running optimal equipment and who have secured wholesale electricity prices have seen their gross margins squeezed requiring a massive deployment of hash power in order to stay afloat. But this month did see a small uptake, the first time since Bitcoin's price boom."
Coinbase Executive Says Customer Data Was Resold By Analytics Vendors
"In an alarming interview on Cheddar, Coinbase Director of Institutional Sales, Christine Sandler, suggested the company's controversial acquisition of blockchain intelligence service, Neutrino, may have been precipitated by a violation of customer data policies from previous Coinbase vendors. 'It was important for us to migrate away from our current providers,' Sandler said. 'They were selling client data to outside sources and it was compelling for us to get control over that and have proprietary technology that we could leverage to keep the data safe and protect our clients.'"
Bitcoin Can’t Be Stopped By Politics – Lightning ‘Torch’ Goes From Iran to Israel
"The Lightning Network ‘torch’ payment has reached Israel after it was sent by an Iranian in a symbolic gesture of peace between the two nations. The historic occasion proves that Bitcoin is truly an apolitical and borderless money technology."
Quadriga Crypto Mystery Deepens With ‘Cold Wallets’ Found Empty
"Ernst & Young identified six cold wallet addresses used by Quadriga to store Bitcoin in the past. Five of those wallets haven’t had any balances since April 2018, and a sixth “appears to have been used to receive Bitcoin from another cryptocurrency exchange account and subsequently transfer Bitcoin to the Quadriga hot wallet” on Dec. 3. The only activity since was an inadvertent transfer of Bitcoin into that sixth wallet last month, which was disclosed earlier."
Here are the data brokers quietly buying and selling your personal information
"By buying or licensing data or scraping public records, third-party data companies can assemble detailed profiles with thousands of attributes each for billions of people. For decades, companies could buy up lists of magazines subscribers to build targeted advertising audiences. These days, if you use a smartphone or a credit card, it’s not difficult for a company to determine if you’ve just gone through a break-up, if you’re pregnant or trying to lose weight, whether you’re an extrovert, what medicine you take, where you’ve been, and even how you swipe and tap on your smartphone."

Blockchain, cryptocurrency firms struggling to open bank accounts
"Dozens of companies involved in blockchain and cryptocurrency are opening up in Malta as a result of the government’s push to be a leader in this sector – but they are encountering resistance when they try to open bank accounts. Sources from company service providers, legal firms and corporate finance companies contacted by the Times of Malta – who asked to remain anonymous to protect their clients’ confidentiality – confirmed that banks were politely declining their business, saying it was outside their “risk appetite”."
Heads I Win, Tails You Lose
"Everything that has shifted in the relationship between State and Market has shifted to prevent a systemic-ending deflationary shock like 2008 from ever happening again. So it won’t. If you have prepared your portfolio to protect you from a nasty deflationary shock like a Euro crisis or a China crisis or a Fed crisis – what I call the Three Horsemen of the Investment Semi-Apocalypse – you are building a Maginot Line. You are fighting the last war. You should prepare for the next war. You should prepare for the Fourth Horseman – Inflation – because this horseman is riding in as a response to a deflationary shock or in the absence of a deflationary shock. Either way, fast-motion or slow-motion, THIS is the vector of the next system-redefining process."
Sunday Wedding Announcements: Till Fork Do Us Part...
"The blockchain marriage certificate program started in northern Nevada counties in April 2018. Sending paper copies of marriage certificates took time (up to ten business days), and sending digital certificates was considered too insecure. The protection provided by the Ethereum blockchain solved these problems, providing a fast and safe way to send digital documents. Now, blockchain marriage certificates are gaining acceptance across the country."
How Blockchain is Driving the Fourth Industrial Revolution
"Take a concrete example: You leave your home on vacation. If you have an IoT connected thermostat it could sense a change in temperature while you are away. If it senses your home is becoming too cold because of a sudden change in weather, it will communicate with an AI-powered heating-system, which would know you are on vacation and understand that there is a temperature dive that could kill your houseplants or freeze your water pipes. It would then decide to turn the heat on in your home, without you having to give it that instruction. Meanwhile, Blockchain technology would record all this and notify your mobile device, which alerts you to what has happened."
