@Crypto_Slice

“I landed in Argentina with both Dollars 🇺🇸 and Reals 🇧🇷… On top of that, had problems running my traditional card in most places. But then my friend showed me Kast, I was able to make a digital card in a couple minutes, linked it to my Uber app, and have been paying for just about everything for the past 10 days just by transferring USDC. 10/10 recommend.”
