The post quoted above is right since if I myself have earned 1M$ from ethereum's ICO, why would I share it to the public that I earned that amount of money in ETH ICO? For me if I were in the place of the one who earned 1M$ from an ICO, it is the same as saying that "I have a lot of money on my crypto currency wallet, rob me if you can." To be honest, I myself havent earned that much of an amount from an ICO but those who did would not post it here.
