"at some point there will be a run of 100 and the 15000 guy will go stone broke."

It is far more likely that an advantage of 3 tails will always occur before a run of 100 heads does. The tiny bankroll will be wiped out before that "at some point" run has a chance to happen.

Hence, the whole point, you need a proper bankroll to weather the bad streaks in order for the long run expectation to occur.

PS >>>>> To keep risk to the casino at an acceptable level, with a $200 bankroll and a 1% edge, the max bet should be around $2 dollars, not $100.
