What are your thoughts about this card?
Can you spend your coins on the fly?
Really offering 8% cashback as advertised?
1. There are already a number of topics on this matter, I think that best one is:
https://bitcointalk.org/index.php?topic=5276231.02. Afaik they do give cashback, but you have a huge amount of BNB deposited there for that. So, for normal mortals, the cashback is 0.1% (iirc it's 1% cashback - 0.9% fees); the cashback is there only when you're shopping, the withdrawals don't have cashback
3. The only fee I am aware of is that 0.9%, which, as you can see, is usually covered by the default cashback
4. My experience with the card
was written here and on that topic you'll find other users' experience.
5. There are alternatives, but not necessarily better and it depends greatly on where you live. Overall problems are:
* others may have bigger fees than Binance
* it's nice that you can benefit of the integration with Binance exchange
* it allows alos on-the-fly conversion of your crypto when shopping, but at least at first it didn't work that good and may have been also more costly, so exchange and top up with fiat is usually a good idea
* Binance's card is actually issued by Contis Financial Services and it's not well accepted everywhere; but it's by far not the only crypto card getting transactions rejected now and then.
Since I think that asking over and over again the same questions is unproductive,
my advice is to continue the discussion in the topic I've linked. Most of OP's questions may already be answered there.
