You may have already heard about Dogecoin if you browse the bitcointalk forum or any other cryptocoin board. The main DOGE thread on bitcointalk was started at December 08, 2013. Now nine days after it has already 158 pages and more dan 250,000 views! This is crazy if you compare the page count and views of the other well know altcoins like Peercoin, Feathercoin or Worldcoin.
Now while Bitcoin prices are going down it might be a good idea to grab some cheap Dogecoins.
