Which of the Bitcoin wallets between the Online and Offline works best?
I prefer to use offline wallets, because more secure. But if you have high volume daily transactions online or mobile wallet good too with small amount you need for transactions.
It depends on your habits using in Bitcoin for daily.
Example you always need to trading Bitcoin every day.
But, you are holding Bitcoin in private key and offline wallet, it makes you more difficult to trading Bitcoin as hold it in wallet of exchange.
I totally agree. Your choice of which wallet to use should depend on your lifestyle and nature of business. As for me, I chose both because sometimes I do cloud mining to which online wallet is more of use. Also, I have offline businesses that require an offline wallet for it to run smoothly. Simply put, the answer is: it entirely depends on your discretion. But, if with such, you have to consider the risks that come along with it. Say, security reasons, efficiency, time value of money, among others.
