Opening packs is one of the ways to get top players in FIFA, but it requires buying expensive points from EA with a low win rate. The document reviews and compares four popular pack opening sites - FIFACOIN.COM, FUTGALAXY.COM, FIFAUTSTORE.COM, and GOLDAH.COM - in terms of steps, supported consoles, pack varieties, win rates, and customer support. FIFACOIN.COM is rated the highest with a 65% win rate and 24/7 live support, while GOLDAH.COM has the lowest win rate and lacks live support.
