My own was a token I bought back then to make a double of my investment and I saw the value dropping and I didn't cut my loss. After a while the token value began to reduce by half at every time it dumped till it went to very low price. I was baffled and made further findings and saw that the team was the one dumping their tokens. I learnt a great lesson to never buy a token that has only one market or trading in on my one exchange.
Lesson learned. This is why many projects are not good to invest in. Just because they are offering it on the sale and they have good promises, that's not an assurance that you should invest in it.
I've seen many times that there were complaints of investors that their tokens were dropping mainly because of the devs first dropping it and selling it for their own benefit. It is very unethical that they take advantage of their investors when their main purpose and plan is to dump it all at once.
