So no one knows for sure of course but many suspect that early mining by likely Satoshi owned wallets (2009 era) yielded some 1.1m BTC, worth >$50B today. So the likely reasons someone sitting in a notional value of $50B+ who hasn't cashed in any of it include: 1. He (or she) is dead (I believe the last confirmed post was 2012?); 2. He (or she) has lost access to these coins; 3. He (or she) has cashed in some wealth from wallets not linked to Satoshi; or 3. He (or she) is sitting on this mountain of wealth and not cashing any of it in. There's the possibility of course that Satoshi isn't one person but several. Let's consider (4). You would need to be an incredibly committed ideologue. We have ways now of essentially laundering crypto (ie by converting it to other crypto through a pooling mechanism that makes it difficult to identify the source wallet for what comes out). It's stated that perhaps Satoshi fears government persecution (eg the tenuous connection to Wikileaks). To me that seems... unlikely. It's not like Satoshi controls the network. Lots of people hold crypto now. Maybe Satoshi just really likes his, her or their privacy. But given that wealth... (1) or (2) become increasingly likely as time goes on. It's fun to speculate.
