Which of the Bitcoin wallets between the Online and Offline works best?
Actually both of them are same because both of them have the fascility of the private key surely .
In case of the online the private key is made by the online Wallet directly and in case of offline we needed to create ourself a private key randomly .
Since we have full trust with the official , so we don't need to take any tension about the online official Wallet .
But if still anyone don't have the trust then he can create own paper wallet in offline and can be use easily like online .
So i think in these both case are better to use According circumstances .
Here in my opinion the bettet thing for us to use official Wallet only because to have official wallet we can use our wallet to store the money safely and there exists no chance to steal by anyone or anything that reasons to loss our money that can be given by the third party wallet .
So always use official wether to use online or offline .
