Lol who said the Lightning network is dead. The lightning network is up by 116% on Litecoin!! It's expanding faster than BTC
i don't think anybody has ever said "lightning network is dead", i don't know what made you think otherwise. they however spread a lot of misinformation about it, such as it being "centralized", "coins being 'locked' in it", it not being bitcoin and a lot more!
the thing is, the only thing these FUDs did were to slow down the progress temporarily and as soon as their bullshit clears, the adoption shoots up again.
as for LTC LN, it doesn't seem to be growing faster than BTC because bitcoin's LN is already too big and is still growing. we only had a surge recently in LTC LN once so far. but all in all it is great to see LTC is still following bitcoin's footsteps like it always has been.
