Welcome to Bankoll Journey - A daily record of building (and maybe losing) a $100 bankroll

Hello. My name is Chase, and I’ve always been fascinated by sports, technology, and the ways they overlap.

This blog is my daily record of using ChatGPT to help pick bets with a mathematical and disciplined approach. The idea is simple: start with a modest $100 bankroll during football season and see where it goes. If it crashes, it crashes.

Last season, I put $100 into my DraftKings account and went on a run. I hit a few big parlays in college and pro football and won plenty of other bets. By the middle of the NFL season, the bankroll had grown past $1,000. But as often happens, I lost it all by the end.

This year, I wanted to do it differently.

As summer winds down, I started again with $100. This morning it stands at $145.16, thanks to Chelsea's big win in the FIFA Club World cup (and my first ever Tennis bet...)

Here is the process I follow each day:

My Betting Rules and Process

✅ Only place bets when the expected value is at least two percent positive.

✅ Confirm the event is actually happening today and all details are correct.

✅ Focus on liquid and reliable markets like NFL, NBA, MLB, WNBA, and ATP.

✅ Check injuries, rest, and context before betting.

✅ Compare sportsbook odds to my own probability estimates and only bet when there is a clear edge.

✅ Stake between one and six percent of the bankroll using a conservative half‑Kelly sizing.

🚫 Never chase losses, overbet, or gamble just to feel involved.

That is the whole idea.

In future posts, I’ll write about how we managed to grow the bankroll by forty‑five percent early on, some of the odd problems we ran into along the way, and how I plan to share the picks we choose each day.
