Looking at the chart, the volume profile is used, this means that at 4 hours the volume profile points to trading at 0.5USD, which is likely to get there, I think DOGE will hit 1USD when BTC is around $100k .
It also depends a lot on things that can't be displayed with graphs. What if Elon musk tweets tomorrow that he is investing $20 million in development for DOGE? He currently keeps posting and I think it keeps the price or goes slightly up exactly because many people think that he has something cooking and is always able to make big announcement. He is obviously not done with the coin.
You are right, what happens is that the charts keep us updated in the short term, although sometimes the technical analysis tends to fail, it gives us an idea of what can happen, and we can get an idea of the trading decisions.
It's like you say, if Elon Musk gives another of his controversial Tweets, the Doge bomb will be unique, I think 1 USD is very possible if an eventual Elon tweet comes up and if BTC fully recovers to a new ATH, whereas that for Now While the market is in this uncertainty of Bitcoin, it is unlikely that Doge will increase in price, even if Elon Musk does his tweets it would cause a pump but quickly dump.
