the current SE precedent is that if SE decides too much RMT gil is in the system, they will clear it from the system, regardless if the person who currently has the gil is RMT or not (they have already done this, and have not stated they would never do it again) - so, not just you, but ANYONE with gil is at risk of losing their gil at anytime SE see's fit to take it until such time as SE states otherwise.
