I'm curious, does CoinJar offer a card that users can utilize for their cryptocurrency transactions? It would be quite convenient to have a physical card to make purchases with cryptocurrency, similar to how traditional debit or credit cards work. If they do have a card, I'd like to know more about its features, such as the fees associated with its usage, any limits on spending, and whether it's widely accepted in stores and online merchants. Additionally, I'm interested in the process of obtaining the card and the level of security it provides for my funds.
