Twitter CEO Jack Dorsey Shows off Bitcoin Lightning Network Node

Francisco Memoria

Twitter co-founder and CEO Jack Dorsey has recently shown off a recently received Bitcoin Lightning Network full node he got from Casa, further showing the entrepreneur’s commitment to the flagship cryptocurrency and its layer-two scaling solution.

The node Jack Dorsey showed off on Twitter is one being sold by Casa for $300, that already comes with a gold membership on the company’s platform, and is already pre-synced to make it easier to set up.

The Casa Node, a plug-and-play solution, is built with Raspberry Pi 3B+ and comes with cables that help users get going. Running a full Bitcoin node helps validate the cryptocurrency’s blockchain, contributing to its decentralization and security.

Since Casa’s node allows Dorsey to participate in the Lightning Network (LN), the cryptocurrency’s layer-two scaling solution, the entrepreneur may also contribute to its liquidity. The LN’s capacity surpassed 50 BTC late last year, and is now over 733 BTC.

Dorsey, who’s also the CEO of Square, the company behind the Cash app, which lets users buy and sell bitcoin, has notably invested in the LN last year, helping it become a reality. Last month, he backed a ‘trust game’ based on it that saw users pass a ‘torch’ worth hundreds of thousands of satoshis to one another.

As CryptoGlobe covered, data from cryptocurrency analytics platform Data Light has shown that 74% of all Bitcoin nodes are located in only 10 countries, with the US alone having over 2,600 nodes.

Behind the US are Germany and France, with 2,016 and 698 Bitcoin nodes respectively. The countries with the greatest Bitcoin nodes per capita were Singapore and the Netherlands, at 17,700 and 32,000 citizens per node.

Head of Capriole Investments: Bitcoin to Reach $100K Within Next 5 Years

Siamak Masnavi

On Sunday (February 16), Charles Edwards, Co-Founder of digital asset management firm Capriole Investments said that, based on Bitcoin's Energy Value, it is likely that the BTC price will reach $100K within the next five years.

As Edwards explained in a blog post published on 13 December 2019, he believes that "Bitcoin’s fair value is a function of energy input, supply growth rate and a constant representing the fiat dollar value of energy," which led him to come up with the following equation that shows how we can determine Bitcoin's Energy Value (V):

V = (Energy Input / Supply Growth Rate) * f


  • "Energy Input (unit: Watts) = Hash Rate (GH/s) * Mining Energy Efficiency (J/GH)"
  • "Supply Growth Rate (unit: s-1) = Annual increase in circulating Bitcoins, equivalent to the inverse of Stock-to-Flow. Calculated as the annual rate (unit: year-1) of change in circulating Bitcoins and then converted to seconds"
  • "Fiat Factor ($USD/Joule) = A constant conversion factor to allow for the fiat USD value of energy"

Edwards then simplied this equation further (since "all units of hash rate and supply rate cancel out"), which meant that he was able to conclude that "he fair value of Bitcoin (V) can be represented as a function of the Joules of energy spent to produce it."

Then, yesterday (February 16), Edwards explained via a tweetstorm that since Bitcoin's Energy Value depends on Hash Rate (HR) and Mining Hardware Efficiency, by predicting what the values of these two variables will be in 2025, we can predict what the Energy Value will be at that time: 

Edwards expects the annual hash rate growth rate to drop to around 20% by 2025: 

He expects the annual rate of improvement in mining hardware efficiency to drop to around 16% by 2025:

He then says that this means a fair value of $100K for Bitcoin by 2025:

Interestingly, he also points out that this $100K forecast is a conservative estimate:
