I thought this podcast decent for any beginners trying to understand Bitcoin or cryptos in general.

"In this “Financial Friday on Satoshi Saturday” episode we discuss what bitcoin the software (wallet) is, what bitcoin the currency (BTC) is, and spend more than a little time talking about globally distributed ledger which stores all bitcoin transactions (The Blockchain). We go over what is good about bitcoin, what is bad about it, and conclude by introducing a concept which we’ll talk about much more in the future: smart contracts."
