I was just watching the mempool for a while, and it felt like waiting in line during rush hour to buy bubble tea... Placing an order (sending a transaction) doesn't mean you'll get your drink immediately. When there's congestion, it's just a bunch of people inserting higher tips in front, and miners/packagers prioritize those who pay more. The rest can only wait patiently. Waiting too long might get stuck, drop out, or you might cancel and resend it yourself. Anyway, it can be quite testing for your patience.

Recently, I heard in the group about some region raising taxes and tightening regulations, then loosening them again. Expectations for deposits and withdrawals on the chain suddenly change, and a wave of people rush in, making the queue even longer... I'm just trying to patch myself: don't rush, wait for confirmation; if it's urgent, try a small amount first, or you'll be stuck for a long time and get frustrated.
