Of course they did, because cryptos are a dire threat to their hegemony. Visa introduced changes to charge more for purchasing cryptos with their cards. Some banks block cards that are used for purchasing cryptos. Sometimes even your credit scored is lowered just for purchasing them.

The banking cartels have a vested interest in discouraging the public from taking any interest in cryptocurrencies at all, and they're only getting started. They will bring out the big guns soon, an you'll seeplain as day that the only thing they're interested in is they're bottom line, which is dependent on them controlling all your finances and taking a cut of every transaction you make.

Cryptos are a way to circumvent their control, and it's like cutting off their oxygen supply, if they become too popular the big banks and credit card companies will wither and die.
