So it means, airdrop will done only for the people who buy and hold tokens till Q2 2018? It is more like a bonus for token holders than an airdrop.
How can people who do not own PRTS token get some tokens to be part of the community?
Holding the tokens until Q2 2018 is not a requirement. So the snapshot will be made at the closing time of the PRTS ICO. PRTS2 will have it's own ICO in Q2 2018.
Agree, from the economic view of an investors it can be considered as a bonus. Technically it is an airdrop though, as the tokens are issued for free to a community of holders of a specific token.
