Can you also remember that meme coin like doge coin has pumped this year and getting very high to close to a $1. Trading or hodling is like a game that can profit or lose but with more care you can profit. A coin like dogecoin was under valued for a long time 10 years back but it took the opportunity of a pump in price and today most investors hodl it and waiting for another pump.
True, but the point to be noted here is that the real reason why some well known rich guy pumped that coin is that they needed to sell their stash. This cannot be proved because of lack of evidence but this is a type of somewhat "legal" manipulation of the market.
Unethical - Yes
Punishable - No.
So take it with a bit of a salt. It is more likely that if you had a stash of Doge already at that time, you would likely not have sold but hoped for even better returns, which is exactly what the rich guy wanted you to do.
This is indeed coming from my experience. Whenever you see any sort of inorganic pump or dump - do the opposite of what the public sentiment would go. You might feel uneasy but truth is that this sector sees way more manipulation than a regulated stock market.
