Yes I have listened to every episode of Bitcoin fundamentals. I am loyal to Preston's show. I have been listening to TIP since 2015 and got into bitcoin because of Preston mentioning it on the show repeatedly in 2016. I didn't believe in it at the time but I respected Preston and thought I was missing something so I bought a little in late 2016. Bitcoin was around 1k at that time and sadly I only bought 100 bucks worth but that's where and how my stacking started.

I was listening to that show before it got really popular. It was popular and one of the higher ranking investing podcasts but you could still chat with Preston on twitter at that time and not be just one of a thousand messages. I used to converse with him and Stig on LinkedIn as well.
