Some people have concerns over security and how the decentralization aspect is affected. Which is a reasonable concern for the most part.
But for me personally, I don’t usually keep a large enough amount of crypto to worry about in my wallet either way and I honestly find it very convenient. I’m currently using the gold card from Bitcoin Vault. These crypto compatible cards are really helping me out with my day to day purchases so that’s kinda cool.
Other than that I think it’s a great way to tradition from bank note payments to full on crypto payment in the near future, slowly bridging the gap between crypto and the mainstream market.
