The gamble is only in trusting the official announcement.
Since they clearly stated that it will be possible to sell unwanted weapons for bronze, many of us (including me) came to the conclusion that, with the ASSUMPTION that the least convenient deal we could get will still be 1 weapon = 1 bronze (SUPPOSEDLY reasonable assumption, or would they really be asking MULTIPLE weapons for a single bronze order back?), then it makes sense to use up any excess reserve of bronze in order to get as many high level weapons as possible, as long as we aren’t forced to use silver yet; and later sell back all surplus weapons to get most of the bronze back.
Edit: I’m still keeping a 50 bronze reserve safe just in case, though.
