1 Dogecoin= 1 USD is a long way to go , we are 1/1000 right now . 1 USD is almost equal to 1000 dogecoins and I don't think we can achieve 1 : 1 ratio too because a lot of traders who just sell a large amount of dogecoin for small profit .
It would be very difficult if you want to touch $1, because the supply level is too much, so it will not be possible, if you have 1 million DOGE you will be able to buy a Lambo easily.
