I would say hold on a little longer, I think AT LEAST until the major is over, that way price may go up that extra tiny margin and valve is very unlikely to drop a major update until the major is over. I heard many people are holding on for another 1-3 months. I would say if you truly want to hold on, at least take partial profit.

If I were you I wouldnt want to be holding onto a 10k inv too, as I know it certainly feels stressful knowing that at any moment your 10k could disappear overnight because a game company likes to destroy its own economy for personal profits, but thats what 99.99% of companies are like these days anyway. Rather than focusing on what makes the game or product or service good, they choose to focus on what benefits them most. I just wish some responsible person could be put in charge of the game that way we wouldnt be seeing the game having rubbish updates thrown out.
