I am nit able to equal them

Since i joined the BBS community. I use to check my BBS balance a 10 to 15 time a day. Every time i found my bbs is running half of my cashable balance. Is purchasing rates are to high because a lot of people seemed focused on purchasing posts. Too get full part of revenues you have to buy your post back . I am always busy in thinking that how can i manage my both Meta Bbs Balance and My Cashable Balance. Should i stop buying my own posts so that i can take Meta Balance equal to my cashable. What do you say folks
