Well, Dogecoin is one of the fastest cryptocurrencies in the market making it extremely convenient for quick payments and micro transactions.

However, there are some altcoins which are a lot faster than Dogecoin delivering near instant speeds for hassle-free payments around the world. There are 3 coins which are fast and are among my favorite altcoin list. Those are Fastcoin, Ark, and Worldcoin. With them, you would be able to make payments without having to worry about slow confirmation times unlike Bitcoin.

While the DOGE is a well established altcoin, and serves its purpose well for tipping and micropayments, it lacks development and innovation, making it stand behind other altcoins which have better features and promising technology.

I'm hoping that someday in the future, a new altcoin would come around with zero block time, having instant speeds for transaction confirmation. Just my thoughts.
