Dogecoin price hit $0.3 right now, and its price is increasing day by day. I think doge price is being affected by bitcoin and etherem. Because the price of both coins is significantly increasing right now. So doge price is followed.
There is no entanglement with Dogecoin and Bitcoin or ethereum, if you looked at the past few months, the price of Dogecoin rallied whenever Elon Musk was tweeting about it and it rallied irrespective of what the market valuation of Bitcoin was at that stage. If anyone is expecting huge value appreciation in Dogecoin all you need to contact is Elon Musk 
.Not entirely true. I mean yeah it has gone up a bit but if bitcoin tanks like it did today doge and everything else will follow. The uptick are a little different but on the way down no altcoin is spared when the honey badger is losing position.
