There's a possibility he is alive and just having fun seeing his brain child attaining unprecedented heights across the globe! Does it make sense to kill the goose that lays the golden egg, that should be the question? What exactly does he stand to gain by dumping the market with his 1 million Bitcoin, does he need to be tutored about the huge potentials of Bitcoin? A mastermind of Bitcoin and blockchain technology is unlikely to settle for less, not after 8 years and the positive outlook of things.

At any rate, Bitcoin has moved on and Satoshi would impact it less dead or alive. In the event of sell of the million Bitcoin, it would jolt the market no doubt for a while, but sooner than later, the market will absorb all that and start yearning for more.
