EtherBTC or ETHB
NOW this one, I think will take off just off of sheer popularity alone. Its supposedly a "Hybrid" Ether and Bitcoin. the solidity and stability and value(future) of Bitcoin with Eth speed and transaction ease. 21 million will be created. Once they hit 100 thousand pre enrolee's or by 2/14/2018 the airdrop will end and tokens will be distributed. I haven't found out how many will be distributed via airdrop though. There are no referral rewards or free tokens for sharing the pre launch. Which is actually pretty reassuring. There is no pyramid type of program to entice people t flock to it. To sign up for the airdrop go to http://clicks.aweber.com/y/ct/?l=Cp4uG&m=kXm5gJ19ts1YO_2&b=zOM_3CjHO4gBuOGJ7OF0fg follow the directions and your registered. I did so we will see how it goes when the airdrop hits.
