I also make my own ecig juice and stacked sats but he was so early on both these life enhancing technologies.
I didn't hear of ecigs till about 2015 and Bitcoin till 2017.
Swapped from purchasing rolling tobacco to making my own ecig juice partly to escape the crippling tax the NZ government had imposed on cigarettes- was paying more tax on cigarette tobacco than I paid on my entire earned income!
One litre of pure nicotine cost ~$200 and is enough to satisfy my addiction for more than a decade.
Am hoping to quit this addiction eventually but avoiding the tobacco tax has been pure pleasure.
His DIY knowledge sharing, self publication ethos and very early knowledge of new freedom tech is impressive - hope he still prospers.
