the higher cmbt lvl the more likely it is to be recoved...sorry to rain on ur parade or bust ur bubble but just about any account around what ur looking for is going to be recoved...its just part of trading account...id say 99% of all accounts over 100 are recoved...u need to make sure the person u buy from is well known and trusted...and be sure to use an MM...even if he wants to go first...u need to have clear proof that the trade went through so that when (i mean if

always play it safe during any transaction...and even more care is needed for accounts liek this
