That's awesome that the cards are a game and also an investment. Hopefully they continue to rise in price. Just know when to sell. Prices in these types of investments tend to peak and then dwindle to nothing as people lose interest and move on to other things (Its the same with hockey cards, pokemon cards...etc). Sometimes rare cards stay valueable but not always. If you get stuck with the cards though sometimes you can wait 20 years and then sell them to people seeking nostalgia for a game they played when they were young. Things often make comebacks in a sort of second wave.
Sounds like you're doing quite well in the game and having fun which is the most important thing. 117 is quite good :)
Hopefully more of these types of game continue to be developed. I think they are great for the platform.
