I like Marinecoin. They are having a artificial intelligence based airdrop right now. the speed of transaction is awesome. Super easy, works with proof of promotion. Check out their website: https://marineco.in marinecoin to the moooon. Transferring mtc to my wallet in just a second. The best part about is %99 of all MTC is fair distribution based on a new coin generation system called proof of promotion called POP. Best of all, It is a self sustaining machine to machine system with a steady growing community.
