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.
I think that is a natural thing, where investors certainly really want a greater return and profit is one of them. Not because investors do not trust the project, because I think every investor must have observed a number of projects that they think have the potential to be invested but I think they complain when what they think doesn't match what happened and they just want to express something that makes them want to share with us about what they experienced.
