The thing about Dogecoin is that I can sync to its network in less than 1 minute. It took around an hour to 2 hours to sync from beginning to present (nearly 4 years!) and then I was ready to transact. Compare that to other coins like Ethereum, it takes me around 5 hours to connect just from a few days ago.... WTF?
Part of the reason it works so well is that the developers don't mess with it. They have a product where the network and the wallets all work seamlessly, and they leave it alone. No need to keep downloading new wallets, no bloat, no changes. It just works.
The more expensive bitcoin gets (and the more reluctant people are to spend it), the more I'm convinced that a coin like doge will be used as an actually currency, for daily use.
