Why do people invest into dogecoin?
because this coin started as a joke, then people liked the joke and stuck around and saw it can be mined and the reward was good. then the community grew and it started attracting a lot of attention and fun memes so more people came.
also it is fast and easy to use and super cheap (fees are 1 Doge!).
there aren't much to it that this, and the huge supply of multi billion is a big downside!
First, it is ranked in the top 15 cryptocurrency.
meaningless when the coin has 100 billion coins around!
Secondly, it is so cheap that if it has a slight growth, you will make A LOT.
correct about it being cheap, specially if you are talking about transaction cost
but wrong about growth. the rise is happening all over altcoin market and it is not specific to Doge or any other altcoin, they are ALL getting pumped. and they will ALL get dumped eventually.
Basically, right now it is not even worth $0.01. The potential in this coin is so huge.
not it doesn't have.
Dogecoin has various use, but I wont list it.
you won't list it because there aren't really that much. there are a couple of merchants who were Doge Meme Fans who added doge and a couple of game selling websites which did that but most of them went out of business because of lack of interest.
