Two months in already since I started using a Ruby card by Crypto.com for my business expesnes. (Amex is still my go to for personal expenses).
I'm very happy with the returns at 220 USD it means I will have just over 1.000 usd within a year at the very least.
Although my initial plan was to convert this into Bitcoin as the rewards are being paid in their native CRO, I think the benefits will be great if I stake more cro and move into a higher reward rate card such as the Royal Indigo & Jade Green which offers 3% instead of 2% on the ruby.
I'd strongly recommend that you use ANY rewards card for your day to day expenses either FIAT or CRYPTO one.
