Cryptocurrencies are both exciting and terrifying at the same time. They have received considerable attention lately, both positive and negative. The present state reminds me of the Dot Com Bubble from two decades ago (for those like me that remember it). Hopefully we have learned our lessons and temper our exuberance accordingly; history does not need to repeat. Like social media, FOMO seems to be driving a lot of our interest. Personally, I have no issue with cryptocurrency nor do I have any interest in having it but am extremely interested in the underpinning blockchain technology and its future potential.
