Don't Forget Your Bitcoin Change!
While bitcoin is commonly viewed as electronic cash, bitcoin users don?t actually receive their ?change? back instantly when spending less than what?s in their wallet. Instead, bitcoin change is digitally redeposited in a change address. What you say? For example, consider what would happen if you went to Starbucks and sought to purchase a fancy $5 coffee. If your bitcoin wallet holds $50, the cashier will retrieve $5 from your account and credit your bitcoin address with $45 in ?change.? However, this change is not available for spending until bitcoin confirmations complete ? ensuring that the funds are delivered to the intended address. This can take seconds, minutes or more.

Russian economist: Russia will buy billions of dollars in Bitcoin (BTC) next month
El gobierno ruso no está dispuesto a permitir que las sanciones económicas unilaterales impuestas por el gobierno de Donald Trump afecten aún más su economía y puede estar considerando una medida contundente para combatir el poder estadounidense en esta guerra diplomática actual. Según Vladislav Ginko, profesor de la Academia Presidencial Rusa de Economía Nacional y Administración Pública de Moscú, el gobierno ruso podría estar considerando la adquisición de 470 mil millones de dólares en Bitcoin como una forma de cambiar parte de sus reservas de fiat a criptomonedas. El respetado economista afirma que dicho plan tendría una ejecución por etapas dada su magnitud, sin embargo, a pesar de no haberse confirmado, sus estimaciones indican que en este mismo trimestre del año, la administración de Putin estaría interesada en comprar al menos 10 mil millones de dólares. .

Bitcoin Price Analysis: BTC/USD Still on Breakout Watch
Bitcoin continues to hover close to the top of its triangle consolidation pattern visible on the 4-hour time frame as it attempts to break higher. This marks another day above the $4,000 mark which is a positive sign for bulls. In addition, the 100 SMA is safely above the longer-term 200 SMA to confirm that the path of least resistance is to the upside. In other words, resistance is more likely to break than to hold or support is more likely to hold than to break. The 200 SMA dynamic support lines up with the triangle bottom at $4,000 to add to its strength as a floor. A break past the triangle top around $4,200 could send Bitcoin higher by the same height as the chart formation. This spans $3,200 to around $4,400 so the resulting climb could be around $1,200. Similarly, a break below support could set off a slide of the same size.

Qtum Completes First Atomic Swap With Bitcoin on Mainnet
Hyperbitcoinization enthusiast and writer Qtum, a blockchain platform that merges the strength of Bitcoin?s blockchain with the Ethereum Virtual Machine to build decentralized applications, has completed its first atomic swap with Bitcoin on mainnet. This is a big, first step for atomic swaps, a feature that allows for on-chain exchanges, or transactions, between cryptocurrencies on two separate blockchains without the need to rely on a third party. For Bitcoin, this is a big step forward in allowing interoperability between other blockchains and itself in a trustless manner. Atomic swaps are not an entirely new feature, as Bitcoin Magazine has reported on a Lightning Network ERC-20 swap with bitcoin just a few months ago.

Crypto Visionary Nick Szabo Says Banks May Scrap 'Physically Vulnerable' Gold for Bitcoin
Computer scientist and cryptographer Nick Szabo says he believes central banks may decide to boost their reserves with crypto. The prediction is one of several made by Szabo at the first Israel Bitcoin Summit, as reported by Finance Magnates. ?There?s going to be some situations where a central bank can?t trust a foreign central bank or government with their bonds, for example. One solution that?s been developed is to have the Swiss government hold it for you ? that?s not a trust minimised solution. The Swiss government itself is subject to political pressures and so a more trust-minimised solution is cryptocurrency.

Why the Winklevoss Twins Have a Lot of Love For Bitcoin the OG Crypto
The Winklevoss twins Ask Me Anything (AMA) session on Reddit grabbed the headlines throughout this week, primarily because of the ambitious long-term belief of Tyler Winklevoss that the market cap of Bitcoin will surpass that of gold at $7 trillion. The twins, who operate Gemini, a strictly regulated cryptocurrency exchange in the U.S., has long been enthusiastic about Bitcoin and the possibility of the dominant cryptocurrency competing against major traditional assets in the years to come. Although the Winklevoss twins have plenty of incentives to portray optimism toward Bitcoin given their holdings of 91,666 BTC they acquired in 2013 when the price of the asset was hovering at $120, the recent correction of crypto assets and a year-long bear market may have led the twins to develop increasing positivity toward Bitcoin.

Breakthrough: Bitcoin and Crypto Exchanges Approved in Thailand

The newly licensed broker-dealers are Bx, Bitkub, Coins and Satang Pro. The move affirms Thailand?s push to become a key cryptocurrency player in Asia where Japan, Singapore, Taiwan and Hong Kong are established hubs for blockchain entrepreneurs. A fifth exchange, Coin Asset, is pending review. According to the announcement, two exchanges were rejected. Both Cash2Coin Company Limited (Cash2coin) and South East Asia Digital Exchange Limited (SEADEX) will shutter their operations by January 14. The Finance Ministry says the exchanges were denied due to poor know-your-customer regulations, and unsafe IT security and cybersecurity systems.

Vitalik Buterin on Bitcoin SV: BSV is a pure dumpster fire
I have my disagreements with the Bitcoin roadmap, PoW, etc but they're trying to do something that's genuinely cool tech. BSV is a pure dumpster fire. BSV conclusively showed that a single block can take more than 20 minutes to propagate. It also had a clear case of a miner mining two different blocks at the same height. They are the laughingstock of cryptocurrencies, a coin borne of fraud, social media images and endless bullshit. If you are satisfied with a solution where the consensus among a small group becomes canonical for the rest of the network, then both XRP or Bitcoin SV are good solutions for you (most cryptocurrency enthusiasts aren't).

French tobacconists start selling Bitcoin - The Bitcoin News
In addition to cigarettes and lottery tickets, Bitcoins can now be bought in French tobacconists. By February, 6,500 businesses are to run Bitcoin So far, there are only six tobacco shops in and around Paris offering the leading cryptocurrency for sale. There are already 6,500 branches in February, Adil Zakhar told Reuters. Zakhar is one of the co-founders of Keplerk, a French fintech group responsible for implementing the service.     ?Some people find it difficult to get bitcoins online,? Zakhar said. ?They trust their local tobacco shop owner more than an anonymous website.? The publication of bitcoins does not take place through the tobacconists. Rather, customers receive a kind of coupon card with a credit of 50, 100 or 200 euros on which a QR code is displayed. By scanning the code, the amount will be automatically credited to the electronic purse. Keplerk charges a commission of 7% on every ticket sold, with the tobacco dealer receiving a stake of 1.25%.

A New Blockchain Project is Generating 20% of Daily Bitcoin Transactions
by cryptocurrencynews | Jan 9, 2019 | Cryptocurrency News | 0 comments Recently, Bitcoin developers noticed some strange activity on the blockchain. Specifically, a large number of unidentified OP_RETURNtransactions were discovered. OP_RETURN is a type of Bitcoin transaction that is used for embedding data into the blockchain. It can be used for anything from proving the existence of some data at a specific point in time (proof-of-existence) to issuing new assets, such as the controversial US dollar-pegged Tether, on top of the Bitcoin blockchain. Over the weekend, it become more widely known that the entity behind these transactions is VeriBlock, which is a project that piggybacks on the Bitcoin blockchain in an effort to better secure alternative crypto asset networks. According to Casa CTO Jameson Lopp and VeriBlock?s own block explorer, VeriBlock has grown to the point where it now accounts for roughly 20% of all daily Bitcoin transactions.
