I don't read Spike, nor the roulette threads. I am also trying not to participate there much as the owner allowed people to doxx a fulltime player, trying to harm or end their career. THAT I cannot support. Why are YOU reading him and if it bothers you, you should say something.
But here is the difference with Spike. 1) No one takes him seriously. It is obvious from his long history he wants to argue. Now before you claim the same of Singer, there were people on this forum like SlingShot who admitted to trying to use Singer's progression system. And surely there were others. The guy wrote 2 books for God sakes.
Also, again, I don't read Spike, so I don't know what his claims are as to specifics. What I have read I don't remember him promoting progression wagering. I only remember him vaguely saying he beats roulette with no explanation. So I have nothing to challenge. Again, if YOU have read something more specific, YOU should challenge him.
