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?
I try not to sell tokens or coins looking in my opinion ICO but try their HOLD.
