* **Keywords:** Consider adding relevant keywords to the description (e.g., 區塊鏈, 加密貨幣, 比特幣持有者, 交易所 or blockchain, cryptocurrency, bitcoin holders, exchange). This will help with search engine optimization (SEO) and improve the discoverability of your content. These keywords would be in Traditional Chinese of course.
