Bitcoin is better-quality money. But I don't think that it 'makes people rich'. Sure Bitcoin can be sold for a larger and larger 'exchange rate' over time... but that's not necessarily a reflection of Bitcoin being better-quality money.

The 'exchange rate' going up, to the extent it increases faster than the inflation-rate, is a result of price-discovery of Bitcoin the financial asset.

However the 'quality-money' characteristics are a reflection of its real world purchasing power, privacy, scalability, usability, transactability and universal trust and acceptance it earns over time.

Those things make Bitcoin 'better money' over time in a lasting way. Buying Bitcoin for 'cheaper' then selling it for 'more' later on in exchange for fiat... is price-speculation. It's not really using Bitcoin 'as money' in my opinion and doesn't count as such.

As far as people being 'late' or 'early' to Bitcoin... Bitcoin is a ~130-year experiment in non-state money. It is year 16 which means there are ~114 years to go so practically no-one alive today will see the last satoshi mined.

The next generation will... but a newborn baby todaywill not live that long so in-fact it is a multi-generational economic experiment.

Therefore anyone alive today with Bitcoin in cold storage... is very early to Bitcoin's eventual outcomes should it survive the next 100-200 years.
