A user-friendly desktop wallet for Namecoin (NMC)?

Yes, such a wallet exists, though it is still in beta: AtomicDEX (desktop version only) supports Namecoin (NMC).

You can even use the built-in “atomic swap” feature to trade your NMC, for example, for Komodo (KMD), which you can hold in the wallet and collect rewards or sell on many popular exchanges like Binance (affiliate link). Make sure you read the instructions first (found under Support). The atomic swap protocol requires that the maker and taker stay online and monitor the blockchains involved.

Bootstrap file to synchronize your Dogecoin Core wallet faster

Update February 28, 2021: Dogecoin Core 1.14.3 has been released and significantly improves the synchronization speed. The method described in the original post below is no longer be necessary.

This article assumes that you have backed up your wallet and updated to the most recent version of Dogecoin Core (currently 1.14.2).

You can find further information on the Dogecoin Discord (in the FAQ section), the Dogecoin Core GitHub and the Dogecoin subreddit.

Let’s not forget that Dogecoin was created as a joke.

Edit 2: I do not recommend using the full node wallet (version 1.14.2) if you’re just getting started with Dogecoin. Consider using a simple mobile wallet like Trust Wallet.

Windows applications: User interface controls too small on high DPI displays

The problem: Controls are too small

You’re running an application on a PC with a high DPI display and some (or all) of the controls are too small. You do not want to change the system-wide scaling settings just to make this application more usable.
