Many legit investors create VALUE by putting in thier money
in a cryptocurrency. And then people who earned free coins/tokens
come in and ruin it by dumping in the sight of quick profit.
Do you agree?
Can't agree with you. Airdrops are beneficial both for the noobs who get the coins for free, and for those who invest in the currency. The noobs get free money, while the serious investors benefit from the price rise, which will naturally occur when the user-base expands as a result of the airdrop. And not all of those who receive airdropped coins dump them right-away. Most of them keep at least 20% to 50% of the coins for long-term.
Agreed on what you have said, Airdrops are beneficial for both kind of people and the true and solid investors benefit from this because when the noobs start to dump those precious tokens or coins real investors would buy it in a very cheap price and both will be happy, the noobs earned some money and the investors will profit in the future. Both people will be happy in this process and when the time all the tokens and coins are dumped by the noobs it is the time for the investors turn to make the price rise again.
