Market observers have found that the investment behavior of South Korean investors is spreading from virtual currencies to physical precious metals, and silver has become the latest speculative target for South Koreans. Data show that 31% of office workers in South Korea hold virtual currencies, of which the 20-39 age group accounts for as high as 61%. However, with South Korea's inclusion of virtual currency exchanges in the scope of personal tax taxation, investment behavior has begun to change. Compared with gold, which has a higher unit price and is more difficult to buy physically, silver futures only require 5% margin, which is much lower than stocks. The fluctuation range of 30% in a single day is also smaller than that of virtual currencies.
