Regarding trading costs, I recently finally understood a certain calculation. Many people only look at the percentage increase but ignore those hidden fees. My own experience is a lesson—my account's apparent increase of dozens or even over a hundred percent, but as soon as I sell, I end up losing money. Where is the problem? It’s all about various fees.

This week I realized that just the miscellaneous costs like transaction fees, slippage, and withdrawal fees eat up about a thousand yuan. In other words, those small gains never really made money; all the profit was lost to fees.

So my current advice is: unless you are confident that a certain coin will rise by more than 20% in the long term, avoid frequent trading. A 10% increase? Sorry, after deducting all kinds of fees, you’re still losing money. Holding for the long term and waiting for a big market move is the way for small investors. Frequent trading may seem flexible, but in reality, you lose more. Calculate your costs and you’ll understand clearly.
