KAST card review, tips, and comparison In summary: Since it doesn't cost anything, definitely get a KAST card (@KASTcard). How can we use or cash out crypto? If you've earned crypto through trading, mining, or yapping, or if you're doing self-custody, you've probably thought about how to cash out your crypto at least once. Going from overseas exchanges to domestic exchanges to bank accounts is a hassle, and if the deposit amount is large, you have to upload a mugshot. (Am I joking when I'm just trying to get my money.....) While looking for a more convenient way to use crypto, I started using crypto cards that allow you to use crypto or stablecoins directly. Personally, I've tried Redot and Cypher, both of which have daily/monthly usage limits and slightly higher FX fees or deposit fees. Compared to other crypto cards, the advantages of KAST are: - Unlimited usage limit - 0% fee for using USD - 0% deposit fee for stablecoins - Low FX fee (2%) Other advantages include: - Ability to open a US bank account (can deposit and transfer within the US) - Free issuance of 2 virtual cards (from the 3rd card, $2 each) - No transfer fees between KAST accounts - Points added for the amount spent (TGE in the first half of 2026) - Up to 4% cashback rewards (points) based on the standard card - Earn 500 points after 5 uses (about $40) - Various designs (Bitcoin, SOLANA, KAST) A tip is that since there are no limits and the USD usage fee is 0%, you will definitely benefit more than 15,000 won for every $1,000 when using dollars for US online shopping, subscription services, or traveling to the US. (I find it a hassle to withdraw, so I just pay the FX fee in Korea) As of the time I'm writing this, USDT is 1,395 won, and the dollar is 1,409 won when buying. In other words, if you deposit 1 USDT into the exchange to buy dollars, it costs 14 won per $1, or 14,000 won per $1,000, and adding card fees or exchange fees means a loss of more than 15,000 won. In short, since it doesn't cost anything, definitely get a KAST card. It's especially necessary if you're traveling to the US or need to use dollars. It's better than exchanging dollars.
