@KeKeYa88 Let me teach you another important life lesson: Spend money on the inside, Spend money on the outside, If you finally get something on the outside, Never spend it on the inside.

@KeKeYa88 Excellent guide! Actually, there are often various arbitrage opportunities with overseas credit cards. I opened a new Visa/Mastercard account in Singapore and received a lot of freebies, including a Switch as a sign-up gift. I made quite a bit of money through various arbitrage opportunities. Later, I found that investing in US stocks was the most reliable option, haha.

@KeKeYa88 You've been so efficient lately! 👍
