Or is there only only one unique Dogecoin?
In my opinion, if Elon Musk doesn't make a tweert then the price of Dogecoin will also increase like some time ago and now it is still quite expensive. because now is an altcoin session so all the community will be focused on the old altcoins like Doge, LTC, TRX, XRP. and several other altcoins that have experienced a pump. so the price of Dogecoin is not affected by elon's tweet.
