I believe that in China, locals use it as everyday currency. [I think]. I saw an article online in where people use it because it;s the most stable coin asides litecoin and other alt coins. The only issue with DOGE coins is that i think every year thousands or millions are issued, so that that's why the price is so low. I am currently holding quite a few but I really don;t use them. I just have them stored in a hard wallet just in case in the future it goes up. Right now there are about 110,714,148,206 coins [to be exact] and the price for just one is $0.0016. Up to you if you want to save them or do as you please.
I believe the next one everyone has their eyes on is AdEx [ADX]. Since they are supposedly going to team up with NEO, it's a definite buy [i would say]. Hope this helps.
