Recently, I found that many people are asking "how to buy silver," and I thought there was such a thing as a silver passbook at Taiwan Bank. I need to clarify first that such a thing does not exist. But that doesn't mean investing in silver is impossible; in fact, there are plenty of options, and the key is to understand what you truly need.

Let me start with an interesting phenomenon. Silver has become popular in the past two years, not only because it's cheap but more importantly because of its uses. Gold is mainly for hedging, but silver is different—solar panels, electric vehicles, semiconductors, 5G, AI data centers all require it. By 2025, with green energy and AI booming, the demand for silver is expected to grow over 20% annually, turning silver from a purely precious metal into an industrial metal. So if you want to buy silver, you're not just betting on risk aversion, but also participating in the growth of the tech industry.

In terms of price, silver is usually 30 to 120 times cheaper than gold, which is friendly for small investors. But higher volatility is a double-edged sword; when prices rise, it can be 1.5 to 2 times gold's gains, and the same applies when falling. I notice that silver's annual volatility is close to 20%, much higher than gold's 14.7%, so if your heart isn't strong enough, you might want to think twice.

Currently, there are roughly five ways to buy silver on the market. The most traditional is physical silver bars or coins, which have the advantage of no counterparty risk, but the downside is a buy-sell spread of 5 to 20%, and storage can be troublesome. If you want more flexibility, silver ETFs are a good choice; for example, the iShares ETF has an annual expense ratio of only 0.5%, with easy trading and high liquidity, making it suitable for medium- to long-term allocation.

For more aggressive strategies, look at futures or CFDs. Futures are traded on exchanges, with margin about 5 to 10% of the contract value, offering high leverage but with rollover pressures. CFDs have the advantage of no expiration date, adjustable leverage, and flexible minimum units down to 1 ounce, with almost 24-hour trading on weekdays, perfect for office workers who want to trade after hours. Of course, leverage is a double-edged sword; if you get the direction wrong, losses can also be magnified.

Another option is buying silver mining stocks, indirectly participating in silver price increases. Mining stocks usually have 2 to 3 times the volatility of silver prices; if lucky, you can also receive dividends, but you need to know how to research individual stocks.

My personal advice is this: if you're aiming for long-term preservation and fighting inflation, physical silver is indeed stable, but you must be able to tolerate 20-30% pullbacks. If you want to participate in swing trading and profit from price fluctuations, silver ETFs or CFDs are more suitable, with high liquidity and flexible trading hours.

When choosing tools, also consider your lifestyle rhythm. US silver ETFs are mainly tradable during Taiwan's nighttime, while silver futures and CFDs are more active during European and American markets—meaning from 8 PM to early morning Taiwan time, just after work hours. Traditional bank products usually only operate during daytime hours, so if you can't monitor prices during the day, you might miss key opportunities.

Finally, a key point is risk awareness. Silver is highly volatile, so no matter how you buy, you must first understand how much you can lose, and then decide on your capital allocation and leverage accordingly. I've seen too many people lose their principal because they didn't understand risk control. Remember: making money isn't about having a lot of capital, but about knowing how to make your money work effectively.
