In terms of utility LTC is nowhere. That means there are no outside elements putting pressure on developers. It's just miners, traders and holders all holding hands and skipping along, and while things stay the way they are there's really no need for any more development which is what Mr Lee has said outright.
Bitcoin in comparison is heaving with conflicts of interest, turf wars, overbearing outside investment and multiple future possibilities and use scenarios. That's what introduction to the real world brings and LTC would be an identical position if it were there too.
The reason behind the acceptance of bitcoin over other crypto and its success is that it was the first crypto to happen, I realized that I did read about it in newspaper but never really studied much about it, only to be very involved with btc after 2-3 years. The reason why BTC will always be superior to other crypto is not only its technical benefits but the already wide belief and acceptance.
it's not only because of that i mean bitcoin isn't the first choice only because it was the first, but simply because the other are pure clone they do not offer anything that cannot be implemented in bitcoin, this is the real reason
there is no groundbreaking altcoin out there, they born solely for the simple purpose of feeding your bitcoin wallet
