Zach,
You seem like a nice guy, so I hope you can have an open mind when reading this message.
My name is Todd Witteles. I'm a REAL professional gambler, and have a WSOP bracelet. You can look me up on Wikipedia. I've also been on national television twice, exposing major gambling scams.
Your "mentor" Christopher Mitchell is a scammer, and he's not a winning gambler. His "system" is bunk, and is mathematically GUARANTEED to lose. Every single credible professional gambler thinks (and knows) that Christopher is a complete joke. The "lifestyle" you see him flash is funded by people who believe in him, and pay him their hard earned money for his useless "coaching".
The Martingale system is not something Christopher invented or discovered. It has been around since before he was born. Why do you think the casinos haven't gone broke if it's that easy to beat them? It's because the system doesn't work.
he Martingale just shifts everything to where you have a lot of little winning sessions, followed by an eventual huge beatdown,. That's exactly what happened to you the other day.
I would love to see you turn a few bucks into a million, but you won't following Christopher Mitchell. He has never shown an ounce of proof that he actually wins at any casino. He simply flashes money. It's all smoke and mirrors. Christopher is a scammer and a losing gambler.
I would be glad to talk to you on the phone, and explain everything. I have a Masters Degree in Computer Science, am 50 years old, and have a deep mathematical understanding of what makes a winning and losing gambler. I would be happy to explain it all to you, in layman's terms if you wish, so you can understand that you're being taken for a ride by a fake friend and a scammer.
If you decide you don't trust me, I will be glad to refer you to other credible gamblers (ones who are not friends of mine), who will tell you the exact same thing.
Hope you strongly consider everything I wrote to you. Let me know if you'd like to talk.
-Todd
