I was reading the other day in /r/cryptocurrency about the lightning network. Some person made a claim I didn't fully understand, and I want to hear whether this is true or not.

Once August 1st comes and Segwit2x is fully activated, BTC and LTC will be able to do atomic swaps via the lightning network. The user claimed that this will force Litecoin's value to go up (and bring Bitcoin down), cause the lightning network will force a 4:1 conversion between BTC and LTC since there are 4 LTC for each BTC. This would then force the price of LTC to adjust to become 1/4th of BTC.

• Is this true? If so, it would mean LTC would be forced to shoot up to $500~ while BTC maybe gets pulled down to $2000~. This seems like it wouldn't happen, cause I would have heard other people talk about it if we knew for sure such a drastic change was coming.

• If it's not true, can someone explain how the lightning network knows how much value something is? Lets say something costs $50 and accepts LTC for it, and I pay via BTC on the lightning network. How would it know the conversion rate, considering it isn't set in stone and all exchanges even list them at being slightly different.

Thanks for your time,
