I haven't heard from him since, but I thought the same thing. When the real estate market was hot years ago, mortgage brokers made a killing and spent it like the faucet would never get turned off. When it dried up, they had hard lives for a while. If I hit $1M USD in any of my holdings all of a sudden, I'd sell enough of it to pay off my house and the taxes on the gain. Then I'd watch to see what the rest would do... but I'd definitely lock in my earnings... if I hit $5M, I'd sell it all, pay my taxes, put about 3M into 3 separate investment vehicles, sell my house, and move...
I'm enjoying my gains with Hive and all the 2nd layer tokens at the moment. We'll see where it takes me.
