I believe that Satoshi Nakamoto originally meant that Bitcoin will either be widely recognized within 20 years or no one cares about it. It's not that Bitcoin's transaction volume will reach what order of magnitude. I think that Bitcoin in 2029 may exist more as a value calibration, just like the digital gold that people often say. By then, Bitcoin's transaction volume may not be very large, but its influence has penetrated into all aspects of people's lives.
