It usually surprise me when I see investors complaining about a good project that didn't increase or providing returns immediately it got listed on the exchange and they term it scam or say different things like rekted.
But the truth is, are these investors investing in the project because they believe in it or are they just in it for the immediate profit and move on? Because if you are investing in a project because you believe in it then you should be willing to HODL the tokens and wait for the team to gradually deliver the project and meet its necessary roadmap before you judge it and not condemn it on its first listing.
they always think that the price will go to the moon after it got listed in the exchange. We should change that perception because cryptocurrency is no a quick rich scheme. The market has cycle so we should expect that the price is not always going down.
