So are you looking for a broker or just a p2p exchange in where you can sell your bitcoins?
I am in need of a bit broker to help me sort out a problem of selling bitcoins face to face one big amount
You should know that a broker and a p2p exchange are very different things, they dont have anything in common.
In a p2p exchange, you sell your bitcoins face to face just as local bitcoins is doing right now if you find a good seller who is able to do this kind of exchanges.
But a broker, do you know what is that? It is a forex broker, and you are able to put long/short positions.
Try to make a good research before starting this kind of threads that are constantly spamming the site.
