According to news on January 15, Matthias Voelkel, CEO of Germany’s Stuttgart Stock Exchange Group, said that the election of Donald Trump and his ambition to build the United States into a “Bitcoin country” are driving market expansion, and his group is striving to Take a larger share of the cryptocurrency space. Although Voelkel did not disclose the specific amount of cryptocurrency trading at the Stuttgart exchange, he pointed out that this amount had tripled last year and accounted for approximately 25% of total revenue. He added that Bitcoin, the world's most important cryptocurrency, accounts for "nearly 50% of this activity." Late last year, the exchange revealed that the total number of cryptocurrencies it holds for clients had reached €4.3 billion. The exchange also said it has successfully attracted more than one million cryptocurrency trading customers, including professionals and private clients mainly from German-speaking countries. Voelkel also revealed that he has personally invested in Bitcoin and said that he was attracted by the tamper-proof technology behind Bitcoin. He believes cryptocurrencies will only grow in popularity, noting that Bitcoin has "limited supply and growing demand from investors of all ages."
