Thaksin Shinawatra, the former prime minister of Thailand, told a local seminar that Mr. Trump might use bitcoin to pay off American debt, stressing that he was not encouraging people to buy bitcoin, but rather reminding them that it was a trend. There are already a variety of cryptocurrencies, and some say there will be more types of currency in the future than there are countries. The Thai people must keep up with the times and understand these changes. He also suggested that the prime minister could instruct the finance ministry to study whether bitcoin could be accepted in Thailand, for example by piloting it in Phuket so that people who hold bitcoin can make payments locally.
