The story of Hal Finney, an extraordinary cryptographic activist (main contributor to PGP), and his idea of “Reusable Proofs Of Work”. He was also one of the first Bitcoin users (downloading Bitcoin on the day it was released), receiving the first Bitcoin transaction ever from Satoshi him/herself!

Coinmarketcap are listing BCH sites as BTC

Under here: https://coinmarketcap.com/currencies/bitcoin/ They have links to https://bitcoin.com/ and https://forum.bitcoin.com/ which are no longer BTC sites; they're BCH sites. I'm not good at twitter and don't have many followers but I've tweeted at them here: https://twitter.com/bitplane/status/955918445014585344 Can we raise awareness of this and get them to change it please?

15 years of BTC Power Law

5 years ago I made a post in this subreddit showing that BTC is a power law: Price=A*days^n, (days from Genesis Block), n=5.8. Many didn't believe me and said the past doesn't predict the future. Well, after 5 years it turns out that BTC continues its power law behavior with similar exponent. A power law is not another formula or model but the same mathematical behavior behind river formation, mountains growth, cities development, GDP vs population, and metabolic rate. Everything important is ruled by power laws, so BTC. BTC is a force of Nature.
