Dogecoin, is inflationary, it means that there is no maximum limit to the number of coins in circulation and thus the coin can inflate infinitely.

Dogecoin needs to cap their total amount of coins at current volume or reduce the amount of newly created coins greatly to make the coin not only more valuable and useful as an actual currency, but much more stable than(currently is) most other cryptocurrencies.

The cap can be applied temporary once the price reaches certain point and then removed if necessary (there was a cap once for a short period of time back in 2014).

Dogecoin developers, please, add a cap to a dogecoin. Let's get it to the moon!
