I haven't kept track, but there is no doubt my collection value is below my invested amount. But I try not to put a price tag on the entertainment value of the competition.
I'm not even sure I could back into the amount I've spent on my cards and assets. I've brought funds into the game in so many different ways -- BSC, credits, venmo/paypal, even trading Magic the Gathering cards for in-game assets. Honestly, it's probably better I don't know.
