A very informative article. Crypto currency boggles my mind !! For newcomers and "tech-handicapped" like me, understanding bitcoin is a herculean task . I agree with you on this -  "Bitcoin transactions are still slow, and get even slower under heavy load, the fees continue to increase, and the developers continue to fight and feed their egos"....  And there is another rule to life. "The higher the rise, the harder the fall" 😊
