He never mentioned how much BTC he had in the first place. Woz's net worth is estimated to be around US$100 million currently, and I doubt he earned even $100 thousand by selling all of his BTC at the peak price (if he did that at all). Apparently, there's nothing to boast about for him lately, and it's a pitiful sight, frankly speaking.
These are the types that usually speak out because they like the idea of Bitcoin, own a couple of Bitcoins at most for testing purposes, and that's really it.
“My goal was to travel to a place like Stockholm, and go to restaurants and hotels that only accept bitcoin, and only use bitcoin when I travel.”
You don't need more than a couple of Bitcoins for that.
That's what I think too. He said it himself that he bought BTC, when the price was $700 per coin, in order to "experiment with it." So, most likely, he bought 5-6 BTC, not more than that. And even if he sold it when the price was $20,000 per 1 BTC, the profit was negligible compared to his net worth at the time.
I'm certain that he considers the S&P a better long term investment tool than Bitcoin itself.
If it was otherwise, he would be buying BTC these days, not boasting that he sold all of it. Although I read somewhere that he said he's not into money, I normally don't believe in such claims.
