"The central bank held rates steady." If you can't tell whether that's good news or bad news, CashLearning is for you. Economic words show up in the news every day. Learn them one at a time, three minutes a day. Looking something up fades. Answering it yourself sticks. ■ 10 questions a day Interest rates, exchange rates, ETFs, P/E ratios, deposit insurance, IPOs - only words that actually turn up in the news. Pick one of four answers and the explanation comes right away. Getting it wrong is fine. Reading the explanation is the part that counts. ■ Try it before signing up Install and answer 3 questions right away. Sign up only if you like it. ■ Today's economy news Not just what happened, but why it happened. A word you answered yesterday starts showing up in today's headlines. ■ A reason to come back Your streak fills in on a calendar. Missed a day? You can bring it back. Badges arrive as you go, and titles unlock from your level and badges. Kaetori the squirrel keeps you company. ■ Points along the way Finish the day's set and a box opens on the spot. You can redeem from 1,200P - that's 1,000 KRW in Naver Pay points. Choose from Naver Pay, KakaoTalk Gift, Olive Young, Coupang or CU. It isn't much. It's a small thank-you for showing up. ■ With friends When a friend enters your code, they get 1,000P right away. If they keep a three-day streak, you get 1,000P too. You can follow each other and see how far you've come. ■ Who it's for - Anyone who stalls on economic news headlines - New investors who find the vocabulary unfamiliar - Anyone who goes quiet when economics comes up at work
