Another great video! I’m 66 and more of a dabbler who is interested in learninng. What I find frustrating is the purchasing system for coins...so many exchanges. I’ve signed up for 3 exchanges leaving rather sensitive data i.e. passports or driver’s licenses, etc which makes a great hacker target. Of the 3, Coinbase is easy but expensive, Kraken was down for over a month for USA newbies, and another one cancelled USA orders. Would be interested in your thoughts here. Thank you!
