I think Everyone has his own goals. Someone is interested in crypto-currencies and blockchain technology, someone is involved in bounty campaigns and he needs to send reports, and someone just likes to communicate.
The same I can say about holding and trading, same about long-term and selling right away, bounties or airdrops, all of this things are depending on a personality of each. So there is no ultimate way, it is just one way, that everybody goes by himself.
