the airdrop for me its super profitable to gained money, even its all free but you need also to support them, what i mean is if you buy some token or coin for better,. i know they dont yet if they success the project i just suggest its get to support them, even its small money you spend in that project but soon your spend money to his project your profit make 3x income.
As I see it, air drop is very profitable, you get to get those coins for free! although at the moment, its value is not that high or what we can say as profit, but it has a great chance that its value would increase in time, and the good thing there is that you
received some of those coins for free. I call that instant profit, now if you see that its price is consistently increasing then that is a good indicator for you as well that the coin you got is actually worth investing with.
There is no question on that, but also you have to be careful in choosing the airdrop as some might give a link for phishing attempt.
When first airdrop was introduce, I was so active but since some has really ask a lot of information and give big requirements, I stop and now I am
busy investing with ICO as I am sure they are legitimate.
