Micro-payments were not enabled by the cryptocurrency itself. They were enabled by the bitcointip bot (or doge or whatever), since they are off the blockchain, so nothing special was needed for this, just your usual centralized system. And if a Bitcoin clone enables microtransactions, it's because it's not big enough and doesn't need to worry about dust/spam transactions yet.
As usual, dogecoiners don't understand the first thing about their own currency. They think "more coinz is better because microtransactions". I can't believe so many people have trouble grasping the concept of decimals.
