I got snookered by the Plastc card developers, along with a lot of other people. Plastc allowed us to pre-order their smart cards, promising delivery in April. Didn't happen. They've closed up shop and are seeking Chapter 7 bankruptcy. And it's been long enough since we all paid that there's no way we can get our funds back by contesting the charges.

Looking back, I can't understand why I thought it was a great idea, because cryptocurrencies now have become as convenient or more so than credit/debit cards.
