I see there are some of the best ways to securely store bitcoins.
In my opinion online wallets are no more secure and faster in transactions. Online wallets are also known as "hot" wallets. A hot wallet is a wallet that runs on an internet-connected device such as a computer, cell phone or tablet. This way of storing can create vulnerabilities because these wallets generate private keys to your coins on these internet-connected devices. While hot wallets can be very convenient in how you quickly access and transact with your assets, they also don't have maximum security.
