I still hold exrn that I get from aidrop. I do not want to sell it yet, because I think it is good in the future. Lots of nice alt from airdrop, but not all. Before joining in airdrop, we also have to analyze to know alt is good or not.
You got a nice point because holding some coins will give you 50/50 either win or lose. Most people do dispose the most tokens they receive but people who have trust to ICOs prefer hold them for a while. Although the crypto currency investment is for the long term.
