The golden grail of investing is to find that investable asset that provides the greatest reward with the least risk. Alas, despite how commonsensical that precept seems to be, many "professional" investors and analysts seem to miss the point. You often hear, those who only see rewards (or lack thereof, ie. "Hey, Ether went up 150% last year!") or those who only see risks (or lack thereof, ie. "Bitcoin is too volatile to make a good investment"). This last point has been espoused not only be novice retail investors, but by global investment banks, the Financial Times, CNN/Money and even the London Business School. I'm actually quite serious about this (Financial Times, London Business School and Credit Suisse) - all entities that really should know better.
