The original comment was not talking about 2x-3x.
And it's true. For comparison look at the all time price chart of BTC, even today with BTC being down 75% from the peak. It's still up 100x from early prices.
Maybe there is some brilliant or lucky trader who managed to string together some 2x-3x swings with no losses and turn it into a 10x. That's still not 100x...
Likewise it was asked if early miners made 10x-100x. Very few did, and only on a few coins. The ec2 whales you were talking about, by your numbers, barely made 2x. Even if that turns out to be a bit low, it's not 100x.
