RE: I had to make FOUR phone calls to my bank to buy a Mac!

That experience must have been a bit unpleasant. You have the money available, and you can't make a transaction in the normal way, even though you're using the physical card payment. For my day-to-day purchases, I'm using the CryptoCard. I get 0.1% cashback, and since I don't pay for transfers from my regular account to the CDC, it ends up having that advantage. Not long ago I received a promotional campaign in which if you made a CRO stake you could get a discount on the purchase of a Mac (I'm not sure of the amounts or the conditions). I've had a Widows Surface Pro for over 5 years now, and it's starting to give me some problems (particularly in terms of battery life). I didn't want to make such a big investment before the end of this year, but I have to start looking for options.
