What could Sun need so bad from the guy that he payd 4.5m?
Sun has every right to blow his money on such publicity stunts, but again, he's unlikely to convince Buffett of the error of his ways. Buffett is set in his beliefs and won't budge on cryptocurrencies. As a value investor, cryptocurrencies are the antithesis of what he seeks. Cryptocurrencies are highly speculative and also highly potentially rewarding.
