Yes, your statement is correct. Dogecoin is very bullish right now and you will probably making money if you hold it for a while. But not nearly as much as you would with any of the "real" currencies. Bitcoin, Ethereum, etc all introduced revolutionary concepts and will probably change the world in a big way. Dogecoin is a picture of a dog. That's literally all it is. It will never make you rich like BTC is going to.
