Risky market too as there's really no guarantee or pattern yet. Besides "Purple is usually #1".
That's the psychology of Winning.
No matter the cost, people always want to be on the winning team.
When I was at university, to make a bit of money I volunteered to be a stooge for some sort of psychological research. We played a game - I don't fully understand the details of it, or if there were details - which ended up giving each of four players a score in terms of prize money (the payment for the research). At which point each of us was offered a choice: The option to choose to reduce each score by an amount of our choice. One of those selections would be chosen, and that was our prize money.
In other words, the choice was between maximising the profit among all players, or nominally 'winning'. I was second after the initial game, so I could have lopped a few pounds off the winner and ended up in first place. Note that there wasn't any prize for winning; all of us earned the amount we earned.
I always suspected that was to test whether people would be more likely to play for the win or for maximising the profit across everyone.
