It depends on the odds of it working, of course. 200k/17m is 1.2%, so any idiot can arrange a bet which pays of 17m with 1.2% probability with at most 200k at risk.
Of course they can. My comment was in context of the parent. Suggesting 8600% return isn't that impressive is ludicrous and ignores the downside. Comparing this bet to ultra-leveraged bets is silly.
