This is a broad and interesting topic in which people's choices are divided.
But what really is the correct choice?
For me , the answer is YES . There are a lot of tokens out there that dumps hard after the first exchange because most people are scared that the price would go down after. A lot of tokens also disappear ICO which results from whale investors to quickly dump it after ICO and observe the trend of the token and the activities of its developers. If you are a plankton like me, the best thing you should do in my opinion is to dump after ICO and buy at the dip and sell later at a higher price, most tokens have this kind of trend after ICO.
Let us also hear about your thoughts. To dump or not to dump after ICO ends?
Yes dumping the coins after the ICO is good to make profits from your investment but it is really not good for that project because when the price falls too much then that project might fails too.And some tokens will go to moon in few months after the ICO so it all depends and the quality of the project and little bit of luck too.
