First, I don't believe Alberto is involved in any wrongdoing. Such insinuations are disproportionate and should be dismissed.
Second, RetiredCoder has shown to be one step ahead. It's not surprising that he has solved challenges of 120, 125, and 130. If he sets his mind to it, he could tackle 135 and 140 as well. Anyone with enough money and the correct mathematical skills could do it. Unfortunately, despite seemingly being wealthy, he keeps the money for himself. If I were him and didn't need the money, I'd donate it to people who advance exploration in these fields and contribute selflessly. I dare say most of them live modestly. After all, history has shown that we live in a better world thanks to the exchange of knowledge. If everyone kept knowledge to themselves, we'd still be living in caves. However, it's his money, and I'm not in a position to tell him what to do with it. The downside is that this discourages general interest, as anyone with a faster method won't share it, knowing a wealthy person might exploit it to get richer.
So, credit where it's due. Peace and love.
