Important Info WHAT IS BIP 91 (Segwit) Locks In! Why It's Not Scaled Yet

Here is some info about BTC future
Bitcoin's miners, the network of computer operators that secure the blockchain, have now been signaling that they will upgrade the code for 269 blocks in the same signaling period, a move that takes the software one step closer to changing its structure to accommodate more transactions.

Stepping back, the move finds miners agreeing to cement the first part of a larger effort to upgrade bitcoin, called Segwit2x.

FEATURES
1.There will be a 336-block "grace period," taking about two and a half days, during which miners have time to prepare for activation.

2.BIP 91 will activate at block 477,120. Theoretically, mining pools will start rejecting blocks that do not signal support for SegWit (BIP 141). In this way, BIP 91 is a "coordination mechanism" that gets other mining pools to follow along or lose out on mining rewards.

3.SegWit could lock-in during the next difficulty adjustment period of 2016 blocks, which takes about two weeks.

These concerns boil down to:

1.Thinking miners might not be running the software they signal. If enough mining pools – over 50% – are not running the software, it could impact whether SegWit goes through or not.

2.Speculating that mining pools might run the correct software for a while, then stop before SegWit locks in.
