The best way to promote a project is Airdrop campaign. Alot of projects are using this way to have a huge community. Every participant much join, like , share their channel.
What do you think if 50000 Airdrop participants help you promote your Project? So cool👍
I checked http://ico.fundfantasy.com/ and also the main site http://fundfantasy.io/ , there written Tokens left undistributed after the sale will be shared proportionally among token sale participants. The more FUNDZ you own the bigger your airdrop will be.
It turns out that airdrop has been prepared by fundfantasy
only, this airdrop applies only to tokens buyers. for those who do not contribute in ico then have no chance.
I think this might be a fair way though it's not really that good.
Airdrop for holders is not more effective than free Airdrop
So I think it's a good choice to airdrop the remaining tokens to each holders.
They will have alot of time to check who eligible. Cheaters will be disqualified
but, I think the simplest and least inconvenient way is not to give them a chance at all by looking at their recording of transactions over ico.
preventing double-ip network can also but not completely effective prevent but can only reduce the existence of double claim token airdrop.
