is coinbase.com is good site i have heard that site is not working properly...? is there any other site we can get good wallet without any problems......?
Don't get a wallet on some website! It's like putting your Bitcoins in some kind of regular bank! Download a 'real' wallet that stores your Bitcoin on your computer or a paper wallet. If you aren't the only one who's owning the private key to your Bitcoins, you don't really own them at all!
