People have rubbished the idea behind cryptocurrency, why would anyone need a card to carry cryptocurrencies, when you have mobile wallets! A lot of these new projects integrating cards into their projects, aren't even seeing the satoshi dream, cards are some of the things crypto seems to bypass, and now people are making a mockery of the crypto idea. Why do I need a piece of worthless plastic, when transactions can be wallet to wallet!
You just forgot that grandma or grandpa couldn't use mobile wallet. Their generation only trust cash over everything.
By the way, there is another solution for this.
There is a company called Tangem which produce smart banknotes for digital assets.
