Have you seen someone involved in such a practice? Ask them why they did it, and you might likely get a similar response. For example,  someone who's just new to gambling might tell you they never knew what to do, so they just decided to shake things up. An experienced gambler may not be practicing this again, but I bet some of them did it in the past, probably for the same reason we are discussing. Like for me, when I did it, I didn't just understand anything much about sports betting, so what I did then was without any idea of the right steps, and I was just 100% submissive to luck.
