My experience of using this card:

I bought and paid with Lightning Bitcoin. I paid about $101.5 and received a card with a balance of $100. Then I tried to add it to the Curve application - who doesn't know - this is a "proxy" service for cards that may not work with contactless payments, but it works through Curve (Curve has KYC and issues its virtual card with the possibility of contactless payment, then it is added to Google Pay, for example).

I had USD currency in Curve App for the card, but I paid in local currency. Curve, as a rule, has an exchange rate "on the fly" equal to the exchange rate. I have successfully conducted several transactions for the full amount of about $46. Due to 1:1 exchange rates (equal to the exchange rate) it took me exactly as many dollars as I spent in the local currency. My balance after that was exactly as much as was spent on the Curve side. That is, the rate was even more profitable than on many cards of ordinary banks!

A little later that day, I dropped $190, I had $244 and I was trying to pay for dinner at the restaurant for about $230. But two attempts were unsuccessful. There is no information on the CoinDebit website except that you can top up to $250. I can assume that the card can always be replenished up to $250 (and maybe more - I haven't tried it), but you can spend a maximum of $250 in the last 24 hours. But that's my guess. I'll continue checking tomorrow.
