Byzantium And The Crusades - Manzikert 1071 Episode 4 The Battle For Armenia

This podcast series presents a new angle on the Crusades based on the book called The Byzantine World War by Nick Holmes. It explains that Byzantium was the main cause of the First Crusade. This episode explores the background to the pivotal Battle of Manzikert in 1071. It focuses on the fierce war fought in Armenia from the late 1040s to 1060s, as the Byzantine army struggled to contain the increasingly ferocious onslaught of the Seljuk Turks.

Please take a look at my website nickholmesauthor.com where you can download a free copy of The Byzantine World War, my book that describes the origins of the First Crusade.

CoinDesk Podcast Network - RESEARCH: Bitcoin Halving 2020… How the World’s Largest Mining Pool Is Helping Miners ‘De-Risk’

F2Pool is the largest bitcoin mining pool in the world controlling 20 percent of the collective computational energy, also called hashrate, on the bitcoin network. On the fifth and final episode of Bitcoin Halving 2020: Miner Perspectives, Heller discussed the economic incentives driving cryptocurrency mining and mining pool operations. 

This episode is sponsored by ErisX, The Stellar Development Foundation and Grayscale Digital Large Cap Investment Fund

Though miner revenue has decreased sharply over the last two years from around $0.60 per terahash to $0.10, Heller explained bitcoin mining continues to be profitable due to the release of more efficient hardware and the discovery of cheaper sources of electricity. Positive movements in bitcoin price is also a major factor, albeit a frustratingly unpredictable one. 

Heller, who operates a slew of his own mining machines, said that without “significant price action” over the next two weeks leading up to bitcoin’s reward reduction, also called the halving, both he and other miners would have no choice but to turn off “older machines.”
