Our two Bitcoin stocks are way up, GBTC (+21% at today's Open) and MSTR (+13% at today's Open). This is on the backdrop of a monster $22,000 to $27,000 move up in Bitcoin over the weekend. (Watching Bitcoin trade continuously 24/7 over a holiday weekend can be festive when on the right side of the trade.) Here is the bottom line, which I will expand upon in the weeks ahead: There are those who are suggesting a $500,000+ price target for Bitcoin over the next 3-5 years. I would write the lunatics off, but one is Catherine Wood, the Tesla guru from ARK Invest. Her predictions and track record have been spot on, not just for Tesla and Bitcoin, but for a host of stocks in a cross-sector she refers to "disruptive innovation." What if she is right, or even half right, or even one-quarter right on Bitcoin? We have two easily buyable exposure stocks to Bitcoin: GBTC and MSTR, both in our core long-term portfolio. They are an alternative to buying Bitcoin itself, and a whole lot easier to buy, sell and hold. For what it's worth, every portfolio needs some exposure to Bitcoin. From this weekend's action, the risk:reward heavily favors the latter.
