Well, that would be nice knowing that there are 21M bitcoins total supply and he has 1-2% of it so that would be around 420,000 btc holdings. That would be huge selling that together will create such down trend for bitcoin. If that will going to happen then we can expect that all things will follow including those huge whales also investing in bitcoin. Good thing they are still holding btc now and I think any moment they will going to sell it all at once.
The article says his assets, doesn't mean that he bought 1-2% of the 21M bitcoin total supply.
So the best thing is know how big his asset is and compute how much he invested on bitcoin. In any case 1%-2% is small though, probably he just wanted to spread out his wealth and portfolio and invested on the next big thing which is bitcoin. and let me quote him from the article:
“There’s very little trust in it [bitcoin],” he said. However, “we’re watching the birthing of a store of value, and whether that succeeds or not only time will tell.”
So he is 'betting' on the safe side here.
