Which characteristics would make any player "The Best"?
Earnings are an indication of "the best" NOT.
1) There are a lot of definitions of "the best".
2) It requires that players are eligible for credit wins. Those in some countries and in some US states are excluded. The last Open championships have shown proof of that.
3) It requires players to be going for wins and credits. Are those worse who decide only to play for fun?
4) Remember the T&Cs: "Credits have no monetary value". Thus, the representation of earnings as US $ may only be justified for real world prizes like USO visits for one player per year. Thus it might be considered a scam in all the other, that is 99.99% of cases.
Thus, it's hard to be or see the best but easy to have fun!
