As everybody knows a lot of ppl have a hacked account problem and nobody can guarantie that u wont be one of em in the future.Sometimes they steal the whole account and change all the details and sometimes when they dont know the SQ they only hand over their items to another char and drain you..But if the char had a trade pass or code which has to be entered for a trade its for sure that ur items would be a bit more secure then u think that this can be done?
