Bitwage does not endorse any particular online, desktop, mobile or cold-storage wallets.
Many Bitcoin users use a combination of various wallets for privacy, security and safety reasons.
Please do your own research about the security (from hackers or malware) and safety (from hardware failure or forgotten passwords) of each wallet option.
We do encourage backing up your wallets and/or the use of multi-sig wallets.
A feature comparison of most common wallets (as of January 2015) can be found at http://www.walletlist.org
