From my simple mind, to all things that happens, is a road that must be driven.

Bitcoin has opened the road for all cryptos here, and the big people there (who knows who is behind all this changes, informations... big corporations through simple people, big investors... ) want to split to benefit more and more.
Maybe it is all true and sides have been maded, but maybe there will be only 2, to see what happens with the other one... whateva'.

The overall problem is simple. Nothing new, innovative, can't be perfect. All altcoins made from bitcoin, can be better, and saw few projects that look so nice and are already happening with less complications as bitcoin (steemit through steem, i like the most for now :-)) ). For bitcoin, being the leader, the opener of the road it is a big test to see if it can grow up better in a way or another from all this tests.

This is the road to maturity, which has a long way down (but not as long as too many see it, if survives in the future).

Remember, all altcoins are made because of bitcoin was made, but that not means that bitcoin cannot disappear if it can't resist at some point.

Thats my view... messy but the truth is around here.
Although 3 coins don't think, as a lot accepted the SegWit... they are just words, we'll see (all the things in the world swings only around money unfortunately, which is power - fqdem).
