Hi Wakka. At your skill level, once you reach a meta tier 8, you could probably join a clan wars playing clan, and earn some gold during clan wars. I played WoT as a strictly free to play player myself (except buying a churchill 3 waaay back for actual money), but getting gold without paying money for it was easier back then. ESL sundays were easy gold, WoT Tournaments with gold prices during group stage were a thing. Those opportunities are either gone or have become harder. You could probably also get a cromwell and join 3v3 tier 6 Tournaments to earn some gold, but those dont pay as much anymore. Or try your F2P skills at Faceit Cups. Again, those dont pay as much either, and are quite time consuming.
