I'm not sure how the liquidity of this crypto is on the current exchanges but liquidity will sky rocket after the airdrop even if it reaches 5% of islanders which of course will drive down price. My suggestion is to hold until March 20's and then lock in your profits and speculate the rest however if anyone believes in this coin succeeding beyond a year is greatly mistaken as there will be more sensible Forks and a flood of new cryptos with the same philosophy will be coming soon.
Leyt me disagree with this detail; it's not so sure the price will drive down after airdrop. Of course it is possible, but it depends; there will sure be some portion of the islander who just see a possibility to exchange this to money. But there will also be some portion who will see a future value on this and buy them. The direction of the value depends on the amount and proportion of both groups.
And if it goes down, when the quick sellers are out of coins.. it can only go up.
And we must remember the history of Iceland; they simply do not trust their current fiat, it has been inflated *a lot* during years. Sure they see this coin very differently compared to 'an average citizen' on most of the developed countries. That's why I specially like this: Iceland might be the only or one of the few countries in the word where this actually could success.
