The market was a lot worse 5-6 years ago. That was before Mythics, before Modern, and before the huge influx of new + old players that started coming in at Zendikar and grew steadily over ISD and RTR block.It was 5 or 6 years ago (or more) now, but I read an article on how, unless you only ever hit the exact high money cards (aka, never picked a dud); that cards rose in value slower than natural inflation.
*shrug* maybe things have changed, maybe the article was full of shit?
Mist: it also seems like you're only talking for the short term. a couple of months, a year, 2 years. That may skew the results some.
I consistently turn 1000 dollars into 2000-4000 dollars on MTGO every few months via speculation. I could make even more if I was less risk-averse. If you show me how to do that on the stock market I'd love to do that instead.
I also make additional money from just simply flipping MTGO cards at 10-15% margins, but that takes actual time in front of the computer where speculation doesn't.
