If you own a large amount of bitcoin, you should save it on a hard drive, which is safe for you, and of course you must own the private key. Conversely, if you regularly carry out transactions, and the number of bitcoins you own is average, you should use an online wallet that will support you a lot of things, and will ensure the time for Your transactions. Because online wallets always set a fixed fee enough to complete the transaction quickly.
