What is the key to making a ton of coins in FIFA 22?
Right now just avoiding the market crashes lol. Which means getting out of investments before 1P EST (in case promo preview packs drop), and also buying the dip from panic sells in case of the preview packs.
I'm not much of a trader, but Meta cards dip on Sunday evenings and rise again the following day.
Also look at good cards that link to meta promo/TOTW cards. For example...that Mahrez card that just came out...good strong links to him (Cancelo, De Bruyne) have risen. Not a ton, but Cancelo was 11.5 before he came out, 15 now. De Bruyne was 60, now he's 64.
Salah is almost for sure gonna get a POTM SBC. It means I'll be looking to invest in good Liverpool links. In the 4-5-1 you just need one strong link, so Rulebreakers TAA is a target for me. He's been dropping into the 160K range (he actually got as low as 135K yesterday).
When Salah drops, especially because he's Egyptian, people will be looking for a good meta link for him. TAA could rise as high as 200K I'd guess. Even someone like TOTW Firmino could be a good option. He's relatively cheap at 64K (though in the mid 50s yesterday). He's out of packs, so supply is limited. He's Brazilian which opens up plenty of hybrid options in the middle, and he's a decent CAM with 5 star skills.
Even if he only rises to 75K or so, that's still potentially 10K profit per card.
Alternatively, for easy investing, wait until the Player Pick ends and pick up Gold Commons from the Top 5 leagues at 400-500 apiece, and Gold Rares for discard. You may have to sit on them a while but a new player pick/upgrade pack will always come in 1-2 weeks. You can sell commons in the 800 coin range, and Rares in the 850-1000 range. I've been just running through the Top 5 by position and grabbing what I can to avoid duplicates so I don't have to fill up my transfer list/unassigned.
