Well it will always depend on the project, team and everything around it.
I've stopped doing airdrops as they've become for the major part, worthless.
I find myself with numerous dead coins or less than 5$ of worth...
With this course ETH as it is now to sell any tokens for ridiculous prices, is simply unacceptable. It is better to wait for when the market recovers it will all merge for a pittance. In my opinion it is better to take a risk and potentially get a good profit than to sell everything for very little money. Patience friends and you will be well worth all your tokens.
