I don't want to crush your dreams, but the 72m fee is already overpriced due to them having to collect your money in RSGP instead of you buying through their available payment methods, and to expect to be able to sell it for only 3m less is going to be tough. On top of that, iDungeon just came back to powerbot lol, so I don't think you will even be getting 20m for the account, thats just my input though.
