Weekly Crypto Recap

"Cryptoassets were born out of the idea that money should be free from the governments and powerful institutions that have historically controlled it.” ~ Phillip Nunn

Market State

BTC: €3,500.56 | 5,16% since last week

ETH:      €97.05 | 2,79% since last week

BCH:    €124.63 | -29,94% since last week

LTC:       €27.42 | 3,82% since last week

This time around last year Bitcoin passed €10,000 for the first time. Since then it has lost 80% of its all-time high value in December 2017. Currently, Bitcoin is trading at around €3,500.56 which is a 5.16% recovery since last week. Bitcoin’s current bear market began with Bitcoin Cash’s split, when it forked into Bitcoin ABC and Bitcoin SV (Satoshi Vision). The split resulted in an overall negative sentiment in the crypto market. As Roger Ver, Bitcoin Cash supporter put it “In a war no one wins... there is one at less damage and the other at more damage”. One theory on what caused the sharp drop in prices is that Bitcoin Cash supporters needed to sell their Bitcoins to support Bitcoin ABC (BCH) or Bitcoin Satoshi Vision (BSV). Altcoins are suffering great losses as Bitcoin sees new lows. Despite the bear market the crypto industry is booming. Cryptocurrency and blockchain-related jobs are increasing in a rapid pace. Bitcoin’s popularity is rising. The Bitcoin subreddit just celebrated its 1 millionth subscriber last week. Bitcoin is still the best performing asset in the last 10 years.

Top stories of the week


Intel Wins Patent for Energy-Efficient Bitcoin Mining

Computer chip making giant Intel has been granted a patent for developing energy-efficient Bitcoin mining technology. The newly invented Bitcoin mining process could reduce overall power consumption by 15%. Bitcoin mining requires a huge amount of energy. Energy consumption and its cost are the biggest challenges of Bitcoin miners. This is why miners look for the cheapest energy source, which is renewable energy. Bitcoin mining actually helps the growth of renewable energy and encourage new technologies that reduce power consumption. The fact that a big company like Intel is coming to the crypto market, getting their patent and building services is a clear indication of where the crypto market is heading.


G20 Put an Emphasis on Cryptocurrency Regulation

G20 countries have agreed to regulate cryptocurrencies at the summit held in Buenos Aires, Argentina last week. G20 intends to produce a report by 2020 on how to address cryptocurrency impact on the "international tax system". Section 25 of the official declaration reads: “We will regulate crypto-assets for anti-money laundering and countering the financing of terrorism”. Bitcoin was intentionally designed to be censorship resistant, permissionless and borderless. It is doubtful that G20’s attempt will be successful. If cryptocurrency was dying or was irrelevant G20 would have ignored it. Governments cannot ignore cryptocurrency anymore. This is another indication that cryptocurrency is growing and becoming stronger.


Trading Platform Paxful Built a School in Rwanda

Paxful, a peer-to-peer crypto exchange, has completed its second school in Rwanda using entirely Bitcoin donations through the “BuiltWithBitcoin” campaign.

The first school sponsored by the program was built in December 2017 and serves 110 students between the ages of 3-6. The second school was funded by over $100,000 Bitcoin, Bitcoin Cash, Ethereum, Litecoin and Dash donations. It is the first primary school in the entire area dedicated to students between the ages of 6-15. The school will teach children the basics of finance and technological education and introduce them to peer-to-peer finance.

Two Bitcoin Addresses Have Been Blacklisted

The U.S. government has blacklisted two Bitcoin addresses. The two addresses belong to two Iranian men who helped hackers convert millions of dollars of ransomed Bitcoin to Iranian rials. The Bitcoin addresses are: 149w62rY42aZBox8fGcmqNsXUzSStKeq8C and 1AjZPMsnmpdK2Rv9KQNfMurTXinscVro9V. Anyone who sends funds to these two addresses may be subject to secondary sanctions, including being cut off from the U.S. financial system entirely. Still, government can’t force Bitcoin nodes around the world to blacklist certain addresses when validating transactions. On Bitcoin network, there is no blacklist. Bitcoin doesn’t care about government rules, it is governed by its computer algorithm.

The popular crypto term HODL comes from a misspelling on a post in a Bitcoin Talk forum in 2013. The post was written by a member of the forum, named GameKyuubi. Apparently he was drunk at the time of writing the post which was titled “I AM HODLING”. His post has been read over 789,000 times. Since then the crypto community uses the slang HODL to refer to keep holding onto the cryptocurrency even when the prices drop because they believe it will go up and become profitable.  

Quiz answer

What is a Bitcoin blockchain?

The correct answer is : “C”

A block is a bundle of cryptographically verified transactions. A blockchain is a distributed ledger of all of those transactions stored as a sequence of blocks. This ledger is copied and stored across many different so called "full nodes" on the system. A full node is a wallet that stores the whole blockchain which is a lot of data.
