I only know that TRX's price pumped insanely after Sun's lunch with Buffet. That tells everything. He's advertising his TRX. $4.57 million is a huge number to a normal person but it only costs him a fraction of his TRX.
Yes, Justin Sun is the founder of TRON, It's the world top 15 crypto network and web 4.0 blockchain dapp platform, $4.57 Millions paid for have a lunch with Warren Buffett, I think most of the people will said that too crazy and worth it? I think it's a good opportunity to advertise TRON platform, most important is Justin Sun have a lot of $4.57 Million
