BYTEBALL is a cryptocurrency ranked 33rd by market cap.
They are going to give away 98% of all bitcoin through distribution programmes that happen every full moon. The next is at Aug 7, 2017 at 18:10 UTC i.e. 21 hours away
The gist of it is that you'll need to prove that you own a particular BTC wallet and then based on the amount of BTC in that wallet at August 7 18:10 UTC, you get a proportionate amount of GBYTE. Details can be found in the distribution section of https://byteball.org/
Currently you get 0.0625 GBYTE per BTC held. In addition, if you already have GBYTE, you get 20% of what you already hold, so if you have 1 GBYTE, you get an additional 0.2 GBYTE.
You can follow the instructions given in this article: https://freedomnode.com/blog/76/how-to-get-free-bitcoins-with-byteball-and-stellar-lumens-giveaways. Though it was written for the June distribution it still holds true, and can be used as a trustworthy guide.

These distributions will keep happening every month till 98% of all BYTEBALL is not distributed. So, this is a great moment to start and I estimate that these distributions should go on for around 3-4 more months.
So, what are you waiting for! Hurry up as time is running out! And share this with your friends who hold BTC! ;) :)
