Bitcoin has greatly increased in price while the USD has dumped in value exclusively for decades. The dollar has lost 95%+ of it's original purchasing power when they took it off the gold standard. The dollar doesn't hold value at all, it's losing value due to inflation every single day. Just less rapidly than some other currencies that are manipulated to an even higher degree. Do you pay attention to food, housing, or insurance prices? They have increased _significantly_ in just the past 3 years.
