Hi Guys, For those looking to stack bitcoins I highly recommend the Armory Wallet - https://bitcoinarmory.com/ Allows you keep multiple wallets, e.g. a hot wallet for daily use and cold offline wallet for secure storage (super secure and hack proof) Also enables you to create a paper backup and a digital backup of your wallet should the worse happen. Be carefull where you download Armory as a fake clone site has been spotted out there, you can get the link to the genuine version on the main bitcoin site - http://bitcoin.org/en/choose-your-wallet
