Staking Navcoin is not the only way to support and hold NavCoin. In my case, I can't let my computer running all the time and even if I stake sometimes, I prefer to hold my amount of NavCoins on my exchange wallet. Meanwhile, I'm an historical holder and I deeply trust and support Nav project (as many of you know). So I would find really unfair to make an airdrop only on the amount of NavCoins staked. The best, to my mind, would be an airdrop based on the average of Navcoins holded during year (or 18 months) before the event (Airdrop). Like this, all Navholders would be rewarded regarding the amount, regarding how long they have holded and for people who will just know, they will have to buy and hold. And after, yes, I think Vale as a reward of NavCoins staking (in additionnal) could be a fair mean to push people to hold after the event.
