One reason I can see Dogecoin staying a float, is it Has been around for a little while. But, It's available in most wallets, tons of faucets giving it away, and smaller investors can use it as a part of their trading portfolio because of the tiny price. They can actually move around, 1000, 10, 000 doge and make gains. I personally feel Dogecoin is just a token thats good for trading. I assume the fees are tiny as well
