Very much possible! But I believe what Justin Sun did, can be termed as a great promotion of his own coin as well as bitcoin! Mr. Buffet was always a great critic of cryptos and we have seen him hurling negative comments about it in many public forums. Donating bitcoin and TRX to such a personality, is basically an attemp to associate his name with his least favorite things in life! It would clearly get media attention and also enjoys attentions from the similar kind of elite class investors.
It's a clever marketing strategy that Justin executed precisely and cleaverly!
