If LTC is the same thing as BTC it won't matter if BTC's devs fight with each other... If the crypto you are copying is the same and their devs have an issue with block size, that means if LTC were to even get at $10 a pop, the devs would start wondering how to ensure the health of their blockchain network just like BTC's devs are doing.
Yea but they would not make the same mistake as in BTC. If BTC adopts BIP 101 and fails.
Then LTC can adopt BIP 100 and succeed.
This is what I was trying to say.
