Really surprised about this BTC is better than LTC debate guys.
I recommend reading Charlie Lee's last blog post -
https://segwit.org/my-vision-for-segwit-and-lightning-networks-on-litecoin-and-bitcoin-cf95a7ab656bLTC and BTC actually work best when they co-exist together based on the current LTC roadmap. The LTC ecosystem has already been demonstrated to be better at negotiating and reaching consensus than the BTC ecosystem, which gives it the core advantage of being able to out innovate BTC. Thats not a bad thing for BTC, its actually great.
Under Litecoin's current roadmap, if BTC integrates Segwit and the Lightning Network, they would create an instant coin conversion mechanism from BTC to LTC and vice versa. The practical advantage of this in the real world is huge because it would enable BTC holders to utilize the LTC txns to speed up and lower the cost of moving money, while lowering congestion on the BTC blockchain. One real world example of this would potentially mean that Point of Sale devices in stores would be LTC/BTC interoperable, making both coins fundamentally more usable, and allowing BTC to more readily be usable as a day to day form of payment where people expect transactions to occur in seconds not minutes or hours.
Beyond better real world usage, LTC is also good for BTC from the perspective of keeping the development talent around the LTC/BTC platform as opposed to moving into other altcoins. BTC has been notoriously politicized and slow to innovate. From the perspective of developers this generally means that rather than focusing on implementing innovative code, they get tied down in politics. By having that team work with LTC, they can still implement necessary updates to keep the LTC/BTC ecosystem relevant in a world of fast innovating altcoins, use them to prove concepts prior to them moving on to BTC. This means you keep the talent on the chain, and you keep them engaged. An example is the introduction of smart contracts utilizing either MAST or DLC (or a combination of the two if my read on the MIT announcement is accurate). These will likely first be introduced in LTC, before being introduced on BTC. This is key for meeting the challenge presented by other altcoins including Eth head on while not compromising BTC security by ring fencing initial innovation in LTC. I'd imagine the BTC community would want that rather than continuing to lose market share to altcoins.
