Its actually common sense logic. Your "zero risk" view on Bitcoin isnt just debatable; its profoundly naive, and I can bet that the vast majority of people here dont share your opinion and actually understand that nothing is without risk. Need proof? How about history? There is no asset class in the world that is completely risk-free for investors. There never has been, and there never will be.  How about US Treasury bonds or bills? You lend money to the U.S. government, and they promise to pay you back with interest. Is it exciting? No. Will you get rich overnight? Absolutely not. But will you get your money back, plus the promised interest? Quite possibly yes. Thats about as "zero risk" as it gets in the real world. But its still not completely risk-free, because even the largest economy in the world could collapse.
