Very helpful answers so far.
A very good point was made regarding AIRDROPS
We want a very active community, however because of the number of AirDrops we think that people aren't prepared to earn the airdrop anymore.
HOW ELSE CAN WE BUILD AN ACTIVE COMMUNITY THAT SHARES ONE GOAL??
Hope this question isn't too vague like the first!
To build an active community that shares on goal, the developer team of an altcoin must also be active in assisting it's community members when it has problems and the team must always be there to answer questions of their ICO participants in order to have an active community that shares one goal if it is an ICO. If it is an airdrop, make tight rules because if it is too easy, people won't come back anymore. Also try adding improvements in the process.
