well in that case I would like to know how to gain trist till that amount .
and something about that green trust.
will the price of the account really goes up if it has a high trust ?
It probably will, but consider these two points first: forcefully trying to gain positive trust might backfire, and net you negative trust instead; and who would usually be willing to buy accounts with positive trust, when they could pay less for a similarly ranked account with neutral trust? You'll probably just end up aiding scammers, if you go through with this.
