Airdrops & Airdrips

2018: Reaching End-Of-Service, 2019: Discontinued Permanently

What is the difference between an Airdrop and an Airdrip?

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.

Why were Airdrops & Airdrips off-chain?

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.
