Making money by buying and trading Yu-Gi-Oh cards?

Question

Alright, this is for any nerds out there like me who know anything about Yu-Gi-Oh. Alright, so I wanted a little way to make money, and being a fellow nerd I thought about yugioh cards. Heres how it works, some people would pay top dollar for a single card. Depending on how rare and how new and useful it is. So I thought, buy a booster box, sell all the rare cards and maybe a group of commons and pray you get something decent to at least get your money back. To put it in recent terms to anyone who understands. The newest set booster box sells for maybe 75 dollars. Thats 24 packs of 1st edition. Now if you average out that each packs value will at least be $3.50 worth of cards, and hopefully the rare is worth 10 or more, and you get maybe 2-3 decent rares in a box, maybe more if lucky. You sell those cards back on ebay or a good site where you can make money. If all thought out well, you can money off of it. Any fellow collectors and business people's comments would be appreciated.

Answer 1

just save them for about 20 years. like comic books, trading cards will become very rare in the future so if u want money now try ebay. but u could be come rich later on.

Answer 2

I have a set up where I play in a local tournament where no one is any good. I am a competitive player and participate in major tournaments like sohnen jumps. So my deck cost me around 1000 dollars and I've made twice that just be winning at this local tournament. See the prize where I play is 50 dollars store credit and they hold tournaments twice a week. So I go and win and collect store credit over and over again. Then with that store credit which is basically free for me I buy boxes and sell the rares. Ive made a killing and continue to make cash for free. I just win the stupid tournament against people who dont stand a chance against my DAD return deck and it also keeps me in practice for major tournaments where I could also make cash.
