how could he be sued, I think promoting the coins he bought is not a mistake, and also he is an influential person who uses it to take advantage, I think he uses his name and position well, and we would be wise to follow him and know when to get out .
Since he is just an investor who picked Doge as what he decides to invest in, has every right to talk about the project on where he decides to put it in his resources, never forced any one or neither was he paid to do marketing promotion. I believe his a free man on this case without any form of pledging guilty.
