One time I made nearly 20 times my money in one night of playing poker
I mean, I used to have a poker game pretty regularly with some friends and friends of friends. We'd basically just play until one person got all the chips, but we also allowed buying back in once if you were out before 11 PM. One night when it was especially big, we had a lot of people playing and a bunch of them bought back after going out quickly, and I happened to win that night.
Also, the buy-in was $5, so I won like $95 total
Notice how you can make the story sound really impressive or really piddly depending on how you decide to count it. 20x ROI sounds crazy! Winning less than a hundred bucks doesn't. Also, probably over all the games we ever played I came out about even or maybe a little ahead. I'm okay at poker compared to my friends who played. Not amazing, better than average maybe. But there was no amount of losing that would have represented an untenable risk for me.
Similarly, this article is describing the gains from a single bet in isolation. When you say $120M it's, well, more money than most normal humans will see in their lives (though probably the average income here is more like the top quartile of US incomes), but when you say it's like maybe a 2X ROI on that bet, which represented like sub-5% of the assets of just the wallets making the bet, which I doubt even represents the total assets of whoever owned those wallets (Which could also be jointly-owned), it's a lot less impressive. I'm not sure why it's even worth reporting on unless your goal is to push Ethereum through this kind of number-jiggling for the credulous
