I dont know where you hear such information, afaik, Trump has held lots of press conference and none have ever asked him questions regarding his intention on Bitcoin. They're still working on the mistakes of the last administration, maybe after that the president would move ahead to matters on Bitcoin and cryptocurrency. I've not seen or heard of world leaders discussing Bitcoin, they've been holding meetings on peace and ceasefires. As for your information, Japan invested $1trillion in the USA to fund quantum computing.
