As of February 15, 2022, the U.S. dollar has lost 97.58% of its purchasing power against bitcoin over the past five years. Thus $1 is now worth just 0.000023 BTC.
Consequently, as the dollar’s purchasing power has weakened, the amount of satoshi that can be bought for a dollar has continued to decline, in contrast to the rise in bitcoin value.
Between February 1, 2020 and February 1, 2022, the number of satoshi that could be bought for a dollar decreased from 10656 to 2638, a decrease of 75.24%.
In addition, over the past 50 years, inflation has reduced the value of the U.S. dollar by 85%.
