The PoW system posses some kind of scalability issues on bitcoin and we all know it.
PoW is not a scalability problem.. asics do not ever see transactions.. it doesnt matter if a block has 1 transaction or a million transactions an asic is still going to see the same length hash.. so scalability is not a PoW thing at all.. they are two separate things entirely that do not impact each other
The LN has come to augment this flaw if bitcoin. Yet, some persons like Franky1 believes that LN is not bitcoin and not exclusively for bitcoin because it doesn't run on blockchain.
there are thousands of people that dont use LN for many many reasons. they are just too shy to point out the flaws due to the absolute abuse they would get from the LN fans. i simply do not fear or care about the LN fans, so i dont fear speaking out about their flaws and fantasy dreams of utopia.
its not just about not running on a blockchain. its EVERYTHING about LN thats bad.
its the data packets that go between channels are not actually raw transactions that bitcoin would understand.
its that the channels are not audited.
its that the denomination LN uses is not sats or btc.
its the factor of requiring to lock(stake) up coins to then play with pegged different denominations on another network
its the liquidity issues bottlenecks
its the middlemen routing problem
its the lack of sovereign control due to co-signing and middlemen
its everything.
LN has not fixed anything because LN has MORE flaws than bitcoin.
the liquidity problem stops payments from being sent around for any useful amount.. yes great in utopian dream of wanting to spend 2cents. but useless if your locking up say $1.2k for a couple months and wanting to buy pizza every day for 2 months, i guarantee you, you will not successfully fulfil every pizza payment in 2 months. for many reasons
With the privacy concern about Bitcoin, anything that isn't bitcoin would always be treated with care and that is why BSV of btc hard fork is not seen as bitcoin.
What I am sure of is that bitcoin will unanimously undergo some kind of reforms if it's to serve as a complete currency.
oh and LN is not more private. they literally have to publicly announce their channels just for routing to function in their current iteration of their bolts(facepalm).. just wait until regulates see which ones 'route' and then make them have to become registered MSB, simply for making payments on behalf of others for a commission(yep LN is ripe for regulators to get lots of licence fee's)
as for 'currency'
bitcoin IS recognised legally as internationally wide currency by many governments(but not common man in their daily lives) which is where governments managed to slide in their jurisdiction to then treat businesses swapping fiat for btc as currency exchanges rather than retail merchants buying selling product.
but you might mean treated as common currency by common man in their daily life where people have actual daily utility. there are many many ways to achieve this. (unlike the LN fangirls that pretend they are the only 'solution'(facepalm). and FALSELY pretend i am trying to push and enforce only one solution in the opposite direction to LN. sorry but there are many ways to help bitcoin grow. and i mean bitcoin. not other networks brand stealing, and no its not just a blocksize debate like the silly fangirls ignorantly think)
