Hey guys.
What do you think is the best online wallet coinbase or blockchain?
I really do not whant to lose my coins same as mgtox or whats the name.
Between the two, blockchain.info wallet is better.
Coinbase works exactly as same way as mtgox, and you don't have the private keys of your bitcoin.
Blockchain.info works differently. The site keeps the an encrypted version of your wallet file only, with both decryption and encryption done within your browser. And so you are the only one having the access to your private keys.
