Do you really think a 29 year old would be able to change a dinosaur like Warren Buffett's <88 years> view on anything? Donald Trump is the typical "Know it all" American and he is currently the President of the USA to top that, so Justin Sun has almost zero chance of even having a meeting with them.
Both Donald Trump and Warren Buffett have a army of financial advisors to give them the wrong advice on matters related to Crypto currencies.
I would much rather have someone like Andreas to deal with politicians, like he did with the Canadian senate.
