Crypto cards are gaining serious momentum — and they might just help clean up digital finance's dirty reputation, according to Blue and Green Tomorrow.
Cryptocurrency cards, which work like your typical debit or credit card but are funded by digital currency, are showing up with a greener twist. Thanks to blockchain networks shifting to cleaner tech like proof-of-stake (PoS), some crypto cards now come with a significantly smaller pollution impact.
Why does that matter? Because crypto mining — especially for big names like Bitcoin — uses a shocking amount of electricity, much of it from dirty energy. Some estimates compare Bitcoin's annual energy use to that of an entire mid-sized country. This power demand doesn't just strain energy grids — it also drives up electricity bills for everyday people and contributes to the air pollution that harms our communities.
