Hmm I used it to take public transport like the bus and train. I am at the Indigo tier, so I get 2% rebate in CRO for my transactions. I use the traditional banks' cards for other purchases because they offer better rewards, e.g. cashback (in fiat). It's a debit card so I need to top up fiat before I am able to transact - so far there are ways to do so without fees.
I use crypto.com to DCA my BTC, no fees as well when from transferring fiat from my selected bank account to crypto.com. As for the buy/sell on the app, there are "no transaction fees" unlike some platforms but their bid/ask spreads are not very competitive so I guess that's where they make the profit. But I am ok with that - custody/security is more important than solely going for the "cheapest" platform. They have also their own Exchange and DeFi wallet but I hardly use those functions.
Oh, okay... Thanks for sharing your experience!
I thought that you said that you have more different crypto cards, except the Crypto.com card...
Cheers!
