My Vanilla Mastercard keeps getting declined during online transactions, and it's incredibly frustrating. Should I register my ZIP code and address to resolve billing issues, or is it better to just shop in-store? What actually works best for these cards?

The crypto market is growing every day, and new coins keep coming out. But I’m wondering—when will crypto become as easy to use as a credit card, where I can just tap my hardware wallet to pay or receive money, even without the internet, by using my phone to connect to the blockchain?
