For your information, Coinbase is online site and wallet. Coinbase is easy to use and very user friendly and best for daily transactions. But you should not place all your coins in Coinbase. As it is online wallet, they dont give you private keep. Only best for using it to make transaction as they do not deduct transactions fee.
That's right. The number one mistake people make is putting all their fruits in one basket. In this case, They stored bitcoin in web wallets and end up hating the site when their accounts are either hacked, bitcoin deducted or in some cases, Users account are closed and removed with prior notice along with funds. I use Coinbase too and never had issue with it. I stored Majority of my bitcoin funds in a wallet that I own the private keys. Security is everyone's business. add
