If bitcoin becomes million dollars each, or litecoin goes for 500$ and dogecoin goes for 1$ the sheer number of fiat millionaires it could create in the world could be thousands..
dogecoin will never go for $1 each. Over 10 trillion dogecoins are mined daily.
The only thing to do with a dogecoin is give it away before it loses value...oh too late, someone just mined a few billion while you were thinking of how to get rid of it.
