When it comes to wallets, the best one is the one that you are most comfortable with. Your first instinct may be to go for a wallet made by Kraken, but this isn't always the best choice. For example, if you have thousands of dollars in your account and only want to carry around a few hundred bucks on your person at any given time, then a regular wallet will work just fine. If you need something more secure for storing large amounts of money, then Kraken's specialized products are what you should choose.
