Knowing that you could get free coins from Airdrops, would you exchange it once you got the coins or hold it until the vslue rises up?
You will depend on what token it is. Of course you need to know what is happening to it, if it has a chance to rise up, or not. If not, you can exchange it already so you won't waste your time waiting for nothing. You need to be smart in holding and exchanging the tokens that you have so you will not be regretting the decisions you have made.
