Don't be too greedy maybe that's the right word to describe it, shiba just wants to build the hype that's happening right now, remember we're still in a bear market so I assume this is just a temporary pump. I hope I'm wrong.
If he can sell some of it, that would be great because sudden pumps like this are sometimes a trap and you might not gonna see it again, so it's better to take advantage of the current situation to gain some decent amount of income rather than wait for the right time to sell it all at once. They have some major updates coming on but that's not guaranteed to increase the price as soon as they implement it and to be able to get your capital from selling some of it right now, is the best decision you could ever make.
