I have many friends on facebook who is selling TBC or The Billion Coin around 200 to 400 usd at first i think this is not scam but i do some research here in bitcointalk forum and other bitcoin blogs that tbc is a scam, From now the sellers of tbc or the scammer saying that the buyers will get a huge amount of profit they just waiting for the exchanger of tbc 
They are just attracting the people to buy that shitcoin they keep saying that the exchanger will release soon and all of the tbc owners will become millionaire because of it's price lol.Some TBC members tried to get it listed on CCEX. Unfortunately, it didn't get enough votes to make the cut. Some members wish it to get on any regular exchange but it's odd that there's a large number of them though who're against it. I just pity those who bought it at such an astonishing price! They will just marinate in unending frustration for it to be converted to fiat. It's depressing.
