    Somehow I missed you had a website when I found your videos on youtube in 2017/2018 and just now found your new videos and your website today. I did the classic unplug everything early summer 2018 when crypto took a dive and FUD was everywhere and of course regret not keeping them running and upgrading as I was able to. I’ve been back into it for the last 2 months and hopefully wiser this time LOL.

    Very glad to see you are doing well and still educating us!
