Investing in poker players can be extremely profitable depending on the "plan". Generally speaking the more games in a plan the less the risk. For example, I cash roughly 34% of the time so the chances of me not cashing in any of these tournaments is 0.66*0.66*0.66*0.66..(100x times) or basically 0%. I win first place in about 8% of the tournaments I play in so the chance of me winning at least once during the 100x sample is (1-0.08)=0.92 0.92*0.92*0.92.. or 1-(Math.pow(0.92, 100)=0.9976. The true percentages of wins could range over 100x samples from between 2.2% to 13.2% meaning I expect at least 2x wins out of 100 games and upwards of 13x wins. In addition to first place wins I cash roughly 34% of the time so I expect to cash between 24% and 48% depending on variance over the 100x games. Having just 1x win over the 100 samples would mean between 40% and 60% profit for investors.
