This was one of the best webinars I have seen on cryptocurrencies and the blockchain.  It covered the blockchain in detail, problems with certain cryptocurrences and the advantages/disadvantages of other digital currencies.  Whether you are a beginner or have advanced knowledge, this will be helpful.  The webinar covered Initial Coin Offerings and I was shown technology not yet released in the market.  It is definitely worth your time.  Here is the link to register for their next webinar :
