OK, I answer:
- You should observe the sentiment on both sides.
- If the final Segwit2x version is fully compatible with BIP148 and gets support from 80% as announced then I think for now there will be no chain split and the outcome is bullish. Buy/hold.
- The worst outcome is an UASF BIP148 with more than 15 but less than 35% hashrate support. That will result in a chain split almost surely, with BIP148 being the minority chain in terms of hashrate but probably majority of users. Turbulences ahead. Sell/Trade the swings.
- BIP148 with 35%-50%+ has a chance to get a majority of miners on board. That could result in a chain split but here I think there will be a chance the BIP148 chain wins at the end because of user/economy support. However, I expect turbulences and a price drop. Sell.
- BIP148 with 50%+ even without Segwit2x support would be sure to win, but probably won't happen. Would be bullish however.
- BIP148 with <15% has no chance. So the legacy chain or an incompatible Segwit2x chain will win. If that means that the stalemate continues, I consider it bearish. The price evolution of a winning BIP148-incompatible Segwit2x chain is difficult to predict.
