BIP148 results in a soft fork of the legacy chain.

Thanks Eric. To be clear, I am not advocating a contentious hard-fork. I am unclear this approaches impact on the mining landscape as it is today.

Please correct me if I am wrong here:

For BIP148 to avoid a chain split, we are expecting Bitmain to move its hashpower, and sell chips to miners with BIP148 compatible software; we expect them to do this almost immediately.

This sounds like we are aiming for Bitmain to concede defeat here. If there is even a week delay in this concession, the Segwit chain will see extremely slow blocks, and even worse fee pressure than we see today.

Questions:
1. What specifically will Bitmain lose if they don’t play ball, or are slow to switch?

2. Can you describe what the mining landscape looks like without Bitmain if this plan does not go as you expect?
