How to create bitcoin wallets online
You can create bitcoin wallets on www.bitaddress.org
You will get 2 keys – private key and public key. You need to protect your private key. This is required when you want to spend bitcoins from your wallet. If you want to recieve money from someone, you need to give your public address to sender. You can think of public address as your email. People can send you email but can not see your inbox. Same way, people can send you bitcoins using public address but they can not spend bitcoins from your wallet.
