As it is really hard to get first merit from jet cash. Although It is not impossible for a good poster. I have seen here in form that some of our senior merited without any research on post history of the receiver. They merited for that particular post and judge the receiver from that post only which is not good for the forum. Because now the first merit becomes the most important one. After the introduction of demerit system every spammer wants the only first merit at any cost. For that they make some good posts for time being. So never ever transfer merit without a proper look at the previous history.
