Yin Ge strictly selects US/Hong Kong stock brokers and Singapore's Yingli Securities. Please note that it is Singapore's Yingli, not Hong Kong's Yingli. Hong Kong's Yingli cannot trade cryptocurrency ETFs. Newcomers are best equipped with this, and Silver Brother has used the strict selection recommendation of all well-known securities firms in the market. The specific reasons are not explained in detail. 😂😂😂
