Opened massdrop account but closed it soon as realized no PayPal. Never use credit card anywhere unless emergency and then only select airlines and rental cars. Restaurants and hotels cash only and that's what people I knew in credit card security department advised to me. It's not a matter of if but when a credit card will be compromised.
Well i'm guessing that security counsel lives under a rock for UV protection. lol. You're credit card is covered by the Co in which it was provided from. There is no risk. You can be hacked any time if you're a target. It's silly to live so paranoid.
