So you got demoted.
Dont worry too much, keep posting some good post and eventually you will get merit also. You might have been posting too much in the bounty section and you are now back to be a newbie again.
Even through you might have posted in the wrong sections or just been unluckily not to have got some merit on your journey; you must likely have gain blockchain experience after you join Bitcointalk or the crypto currency world general.
See it as a new start. You now got the chance to prove you're knowledge about Bitcoin, Blockchain and Cryptocurrency.
Make some good constructive post and after some time you will start to earn Merits.
