Honestly, don't worry about what the CEO of "x" company is doing now or in the future, because they certainly aren't worrying about you. They live completely different lifestyles to the rest of us and will be in VIP world for the rest of their lives unless they are extremely reckless with finances (unlikely). The current CEO will be wise enough to have a large and diversified portfolio with a majority outside of the world of crypto. In fact most of his wealth will likely reside in the form of Coinbase shares, which will produce a steady growth or pay out dividends from the profits that are generated. It can be hard to dislodge a market leader, so that's most likely what Coinbase will be focusing on and trying to identify or buy up any potential rivals.
