[question] should i unpack my Booster Pack

Unpack, so you can trade double cards for badgemaking later or use cards for trading against games.

you could get foil ;)
and usually the price of the pack is the same as selling the cards (for those packs i got anyway)

Unpack them in case there's something useful in there, plus some people take cards as trade for things.

That depends on what you want to do with the cards. If you just want to sell them, compare the price of the cards with the price of a booster and take into account the fact that Valve & the devs takes a cut for each transaction (so selling 3 cards for 0,07€ is worse than selling a booster for 0,21€). Also, make sure that someone actually buys the boosters for a particular game.

unpack boosters with higher value then ,05-,06.

Gotta unpack them all.

thank you, gonna unpack all of them
