I think it is clear that he is not "into" Crypto currencies, but he does not mind getting profit for free. The $2000 is insignificant, compared to his other investments, so it does not bother him at all.... he can just poke a finger at it and wait for it to Moon.

I do not like Gold & Silver and stocks and bonds, but I own some of it, because I NEVER put all my eggs in one basket. He can decide what percentage of his wealth must be in high risk investments like Crypto currencies, so let it be.

Now, he is seeing that bitcoin has real value in the market. And it just shows that even if he didn't shell out any money nor believe its existence, he's seeing the equivalent amount of his bitcoin holdings in $s right now. This is one good example that even if you are not bitcoin nor altcoin believer, cryptocurrencies will continue to exist and be traded in the market.
