Come to think of it, there are so many advantages of having a crypto wallet versus a physical wallet. You can carry your crypto wallet anywhere as long as you have your phone with you and you will be able to use your funds there just the same way you do with the physical wallet carrying cash on it. If you carry more than $10k at the airport, you have to declare it with customs. You don't have to do that with a crypto wallet.
The wallet of coins cannot be confiscated by a court for debts, alimony, etc. The law has a blind spot here.
Can you add some more please?
