There are many I like but I gotta go with Preston since he was the one that first convinced me to buy Bitcoin back in late 2016. The good old days, before they hit the big time and I could talk to Preston and Stig on LinkdeIn. I really enjoyed the investors podcast and had heard of bitcoin but like most at the beginning thought it was a scam but after Preston mentioned it about 3 times I decided I must be missing something and bought some. Sadly only 100 bucks worth and didn't buy again until it was 15k. Haha.
