some people are against it,
nobody is against Lightning Network.
there are two people, those who don't understand it or understand it a little. and those who are threatened by it. the second group is attacking LN
Some unknown however (for me): cost of opening a channel, what is a channel does not exist between me and the store, etc. but all things considered, Lightning Network is an exciting project I believe.
don't fully understand LN but here is what i know:
you don't open a different channel with everyone. you open a channel then connect to others.
for example you have 50000 satoshi in your LN wallet. you pay 19113 satoshi for a cup of coffee ($2.10) then you see a game skin you like and buy it with 9905 satoshi ($1.05) and since you love me so much you donate me 1 satoshi to my LN invoice.
now you have 20981 satoshi left for later to buy some other stuff...
Apparently this plan has already been discussed. Question however: will current mining pool be able to support such size?
yeah, why not. they can increase it to 1 TB if they wanted. that it just a limit and it means nothing as long as BCH blocks are only 200 kiloBytes large!
the problems will start and show themselves when mining of full blocks began and lasted a while...
