After a few days of stablecoin financial management and arbitrage, let's talk about the most genuine feelings. The entire process is actually not as complicated as imagined—connecting wallet authorization, collateralization, borrowing, and transfers all in one go, it took about ten minutes to complete.

But after actually getting started, I realized that the biggest cost is mental energy. The most exhausting part isn't the operation itself, but the feeling of being "kidnapped" by the market. My eyes unconsciously keep staring at the BTC price, and a 5% drop makes my heart skip a beat. Reflexively, I start calculating how far the liquidation price still is. Although there's a safety margin in theory, once the market erupts, that buffer becomes quite fragile. Only then do I truly understand why industry insiders repeatedly emphasize "position management is more important than greedy gains"—being able to sleep soundly is, in itself, the greatest profit.

The interest rate spread is indeed tempting, but don't treat it as a fixed salary. The yield of financial products might be 20% this month and drop to 15% next month; fluctuations are normal. To play this long-term, mindset is crucial: understand it as a tool to temporarily enhance returns by taking advantage of current market opportunities. It's a bit like a side job—take on work when available, wait when there's none. Don't expect it to become a stable cash flow.
