If you plan on holding any coins for the long-term it is best to store them in a paper wallet.

Developers are currently working on an offline paper wallet generator and we need testers! It's built in HTML and JavaScript and is very similar to other paper wallet generators like bitaddress.org and bitcoinpaperwallets.com

There will be many advanced features included in this paper wallet generator, for starters:

- ZIP download for offline generation
- Multiple coin support (BTC, LTC, NMC, PPC, NXT, etc.)
- Security dashboard: Gauge your setup's security level in the hopes of achieving Zero Trust
- Import Keys or Generate your own
- RNG Generation: Entropy collection based on mouse movement
- Batch generation and printing of multiple wallets

Full feature list will be announced, all features may not make it into the initial Beta but they'll all get added before release.
