with the total supply of Dogecoin, I am sure it will be difficult for the price of Dogecoin to increase by $1, moreover Dogecoin was made just to joke, so in my opinion it is not feasible for the price of Dogecoin to increase by $1 and I personally don't believe that the price of Dogecoin will increase by $1 in the future.
Now that is where I still have a problem where one thing does not work for some coins but seems to work for others. I also know that Dogecoin might not be compare to a coin like Ethereum but when it comes to the issue of supply and the amount a coin can get to, I believe this should no longer be an issue for other coins it is isn't for Ethereum. 
I have posted this pics some where else but feels it still fits in this conversation hence, Ethereum has an Infinite supply, No end in sight and yet it can go up as much as $100k as some are saying so why not Dogecoin? I am not a fan or an Investor in Dogecoin but when I hear things like this, it confuses me.
