I recently came to know about this Airdrop called Marinecoin (https://marineco.in/) where you need to do a promotion of the project i.e. perform a bounty and you get 20,000 coins airdropped. It is a community-driven project where a lot of operations are run by volunteers from around the world. The dev’s identity is not known completely yet, but he/she is going to airdrop ~95% of all coin supply to bounty participants everyday in order to grow a world-wide fair share community.The project is a machine to machine payments network that claims to be at least 5 times faster than the Bitcoin blockchain. The time tested project is already in place since 2013. The blockchain will be maintained by an Artificial Intelligence engine called Jarvis. Jarvis is currently under development. Consequently, the coin will be dev-less over time. Thus removing human bias and emotion from the project. It will also be miner independent since mining payoffs are very less thus discouraging heavy GPU wielders from hoarding coins. Most of the supply is pre-mined. There’s no financial risk involved for the community since they are not asking for any money. You can also join their discord server (https://discordapp.com/invite/zpQyDu6) where the dev hangs out to give regular updates and chat with community members.
