Here is a link to a YouTube Video of Martti Malmi (sirius) at a 2014 Bitcoin Conference being interviewed :
He was asked; What does Bitcoin mean to you? A. "Bitcoin is about financial freedom" - a competing currency.
sirius used to be one of forum admins and there is another forum admin wrote his price estimation many years ago. You can imagine that price estimation was very cheap and the admin is theymos.
His post on Reddit.Around that time I measured with a Kill-A-Watt that 1 kWh could get me 160 BTC, and based on that I thought that BTC was substantially overpriced at the 5 cents or so it was trading at. As a result, I also have the honor of selling BTC at the lowest price ever recorded, $0.003/BTC. 🎉
(That "BitCoin" capitalization... such cringe...)
There is no post as evidence on cheapest price theymos has ever sold his bitcoins.
