Most people are here complaining about the dip in crypto and asking when the market is going to recover, yet they are the same people busily dumping all their holdings hard on exchanges. Who should continue holding and stabilize the market for you? Don't be a selfish investor.
Basically they are dumping their coin and then blame the crypto market if that was not their fault and this is such a hypocrite person. They should continue to hold theirself from dumping their tokens. But remember there was a lot of greedy person in the market.
You cannot blame these people, they invested money in their coin, it is rational for them to seek profit and sell their holding at the sign of it. They were lured to investment by the promise of these projects for the possible profit, so holders should not be blame alone here. You cannot take profit if you hold your coin, no? In some point you have to sell it. Marketing and development is under the responsibility of the project owner. They should have a concrete plan on how to mitigate value depreciation of their coins. I see some project do this by implementing bonuses when holding their token. At least they are making an effort to prevent holders in dumping their coin.
