Worth Every Penny

⭐️  ⭐️  ⭐️  ⭐️  ⭐️

I appreciate the hard work Mitch at spintwig.com did backtesting a complex trading strategy for me. His research was worth every penny!

His backtesting not only confirmed some trading pattern suspicions that I had, but he also uncovered a lucrative pattern I had not even considered. I highly recommend his backtesting service without reservation!

I have meetings coming up with my workplace and retirement account holders – meeting with you first has informed my discussions with them and I’m so glad I ran across your services. Best of all I can see retirement as a realistic option for me next year!

I Learn Something Every Time

⭐️  ⭐️  ⭐️  ⭐️  ⭐️

Just because you think you know it, doesn’t make it any less impactful when someone proves it. I love reading spintwig’s posts, even if it confirms what I already knew. Sometimes it doesn’t.

Information is valuable. Data-backed information is especially so. I 100% appreciate these posts. I learn something every time, even if it is to make me more confident in a certain direction.

Home Ownership a Possibility

⭐️  ⭐️  ⭐️  ⭐️  ⭐️

Over the course of six years, Mitch’s advise has helped me pay off all credit card debt, make a smarter purchase on a car and pay it off, and optimally pay off student loan debt.

Before Mitch, I didn’t realize owning my own home was a possibility.  Our talks have helped me purchase a home and pay off 35% of the mortgage over three years.

In meeting Mitch, my point of view on spending and saving money has changed drastically.
