It would need a huge sum of money to push Dogecoin to $1. It is not impossible but I believe it will have a steep chance. And all this ruckus are just hype, I would suggest looking deeper before being carried away from this recent price increase of Dogecoin.
but when it's all achieved you will be able to see quickly the price will collapse. Dogecoin inventory is too large even unlimited. it will be difficult to maintain the price in the market despite high demand.
it has no maximum supply and that means there was cap for coins and it can be mined anytime to be dumped in the market. The demand will not sustain for the long term as it will always be moving on into the another platforms or tokens too. Doge is not having a good sentiment.
