Lightning network will make Bitcoin fastest and one of the cheapest crypto. It will make manny crypto which only advantage over bitcoin is transaction fees and speed useless. It will suck money from them and pump bitcoin. Week ago i found tool to track lightning network developement progress and I would like to share it with you guys. I think its worth to check regularly.
https://p2sh.info/dashboard/db/lightning-network?orgId=1&from=now-6M&to=nowToday sum of opened chanels has value of 95 bitcoins. Its not that much but as you can see it was 75 BTC week ago and chart looks like it could be 200 in next week. I think that ligdtning network developement is speeding up and soonly we will have great news about it and price can jump to unknown levels. And none TA will show that.
Hmm Yeah, the answer is no.
Some problems with your thoughts,
Fees
1. LN default average fee per transactions is $0.06 and that is if only 1 hop is required.
Litecoin average onchain fee per transaction is $0.01
Speed
1. While LN promises ultra fast transactions , it is an offchain system , and any offchain system can process transactions in microseconds.
Such as using any coin on any exchange that allows offchain transfers.
So it has no real benefits over other coins.
Now if you are a purist and think only LN offchain scaling is capable of these amazing speeds
(It's not , but for the sake of your argument.) Even if it was, Litecoin is also segwit infected and as such also usuable on the Lightning Network.
So while LN makes bitcoin faster & cheaper, it still does not make it faster and cheaper than all alts.
FYI:
Just for comparison sake,
ZEITCOIN average onchain transaction fee is $0.0000025 per transaction.
For values under $20 , it is safe to wait for only 4 transactions which is only 2 minutes to be completely finished.
While with LN, you can wait up to 2 weeks to fully redeem any coin transacted on the LN network.
As you can see some alts are so much cheaper and faster, they play on a completely different level.
