This account BTCreward was bought from quikseller , He gave the account negative trust instantly after buying , this is simply scamming as now the account is of no use at all !
Beware and dont deal with him , or do if you agree to accept red trust , ruined account !!
You were given negative trust because it was discovered that you are a scammer. You were given the opportunity to repay the people you stole from in order to get the negative trust removed from your account however you have not done so.
