Pretty awesome to see the times that I was actively buying, and the times (like now) that I'm having a nice growth only by playing. It was awesome when the price was at 1ct/SPS. I mainly got my SPS from other players back then, though. Even had a savings plan going with a buddy.
And yes, definitely confident in the long term success and fun proportion.
The plot shows you your behavior towards the game :)
That is the interesting part for me.
