Lots of dump their tokens on the market as soon as theyre listed on an exchange. There are always a risk in holding, since you never know how the secondary market is going to treat a token. But equally, strong projects with good fundamentals have the potential to appreciate hugely in price.
How better do you think?
It all depends on what you bought tokens for and at what price. I, for example, bought tokens at different times, but, of course, at a price several times higher than now. If I sell them now, I will lose a lot of money. If the worst scenario happens and the tokens depreciate, then I will lose too. It is better to wait for the best scenario. And to be in profit than to lose.
