Some speculate Satoshi has as many as 1M+ Bitcoins. Could he ever spend them without attracting frenzied tx-attention/investigation or spend them without causing a run on the currency? Could he keep his anonymity?
10 years from now with 18m Bitcoins in existence, Satoshi might have 6% of all Bitcoins. Part of the Bitcoin Oligarchy. However, this is not all bad. Larry Ellison is estimated to be worth $36b and his Randian influence (like it or not) on the world is still limited. If Satoshi was worth $36b in 2022, Bitcoin would have a market capitalisation of $600b. Bitcoin would be causing waves, and each Bitcoin would be valued at $30k each.
Some speculate Satoshi is not an individual, but rather a group. Perhaps this group has good intentions and want to make the world a better place. Curiously, Larry's personal fortune is on par with the endowment of the Bill & Melinda Gates Foundation.
Perhaps "Satoshi" might start offering BTC bounties to make the world a better place. Think X PRIZE? A cure for Malaria?
