Yes, until today I have always reinvested everything that I won in the game by buying more cards, I consider the cards I have as a working tool, so I don’t look at their price.
I know I have a good profit, but I never calculated exactly how much and what the ROI.
However, people who start playing always ask me this:
How much $ can I win?
And since I don't know how to answer this question clearly, I am doing this investigation.
Glad my post was interesting, and thanks for commenting,
