Airdrops & Airdrips
2019: End of Service - No more Freebies
An Airdrop (aka. candy) is a reward for doing something. Usually a social media task (Follow on Twitter, Like on Facebook, Subscribe on YouTube, etc.). An Airdrip usually is a smaller (but recurring) reward for continued engagement such as being a member of a Telegram group, staying subscribed to a newsletter, etc.
QoinPro was used as a faucet to collect and store freebies off-chain until a threshold was reached that on on-chain transaction would make sense considering the associated transaction fees of network miners.
