I wonder myself what make ETC/LTC grow?
ETC is not in any development , not in any national program or bank. It have absolutely no usage and it is garbage that allready cost more than 20$
LTC the same garbage with copy-code from Bitcoin Core. And in fact FAKE Bitcoin clone copy.
This is totally and simply not true. ETC has a good development team behind it placed by Charles Hoskinson. There's another team of ETC developers out there who are as good working on the platform. Plus there are other awesome contributors too like Elaine Ou.
ETC is still being developed the an open source way which how crypto should be developed, without any banking partners and all that ridiculous stuff.
LTC has the upper hand because it activated Segwit before Bitcoin. If Bitcoin doesn't activate it, there are BTC developers who are willing to do the switch and develop in LTC because LN, Schnorr signatures and other stuff possible would be more interesting to them.
