I think doge coins have appeal that no one else has. Firstly there are a ton of dog lovers, secondly the currency is fun. The whole numbers with doge coins are extremely easy to use, send a hundred doge, send a thousand doge, as opposed to 0.0001. They are fast and cheap to send, so cheap that it can be used for tips on content sites, for faucets, and anything else. Looks to be as secure as any other currency, with no major problems in the time they were operating. I'm a big fan for sure.
