Any advice? I’m sitting at around 200K and want to make a run for trout and any stubbage will help
Observe the market and learn it's patterns, cards change value too much and too fast for any particular strategy to work consistently,but if you learn the patterns you can anticipate and take advantage of the ups and downs.
Invest in cards that will have higher value down the road. Live series 84 golds for TA series 3. Live series power bats for the event tomorrow. Inning 1 exclusive cards that will later gain rarity and value through lack of availability, same with inning 2. Purchase as many copies as you can of all star, rookie, and veteran cards for impending collections requiring these.
Plenty of long term methods. Beyond that, currently buy low sell high. If you have 200k, I'd personally invest in 79 silvers, 84 golds, and 5 copies of every All Star/Rookie/Veteran on the market (gold and below).
