Despite several Bitcoin forks having been released recently from Bitcoin
gold, Bitcoin cash, Bitcoin diamond and Super Bitcoin, it appears
another hardfork is on the horizon, this time it's Lightning Bitcoin.
Each of the forked coins have their own uses and specific purpose, with
the Lightning Bitcoin's purpose being to improve and speed up Bitcoin's
transaction capability significantly.

LIGHTNING will be competition for bitcoin cash---
so, best to own both, one will just climb higher, more slowly---(probably bictoin cash goes higher more slowly)

google won't go into a new venture, unless it can control 80% market share---
anyway 80% market share is the norm thru-out the industry...
which bring me to bitcoin hardforks----
bitcoin and hard forks, (should be no different) used to control 80% of it's niche---is my guess.
