This is ridiculous - if, and mathematically this is highly unlikely,
anyone else is dumb enough to join this scam and you get sent their
money you are only going to get about $12 back - you make nothing.
This is obvious because if you scale this system down to 2 people you
give the other person $12 and they give you $12 back. Where does the
other $49,988 come from? Thankfully Electone players, being
musicians, have advanced math skills and don't fall for blatantly
obvious scams like this.
