Almost certainly not. The $10,000 [S1] is a one-time grant when your account starts. It does not refill each match or on respawn. Spend it like seed capital.
Sources disagree. MetaForge's beginner guide says it is per round, and MetaForge's own editor note flags the contradiction. Every other source treats cash as one persistent balance, creators describe players going broke, and a per-match top-up cannot fit either fact.
Sources also do not settle whether a new grant arrives when a new season starts. Either way, a FOB at $7,500 [S1] eats 75% of it, so do not buy one on a fresh account.
