I guess Dogecoin is one of the best token you can invest today, But I guess because of its total supply it would be hard for it to reach a value of $1 per Dogecoin. The best thing to do is buy more dogecoins for you to have a high profit.
Currently, i don't have much hope for the dogecoin because there is no particular development from this coin but it's price completely depends and based on the market only. When Bitcoin price starts increasing automatically the price of doge coin will increase.
