If possible from anyone of you please clerify me with iconic point of Lightning Network payments.
In most cases, they are instant and cost way less than on-chain transactions. However, there are many disadvantages such as not being able to receive payments right after opening a channel, payment routing failures and having to be online in order to prevent the other party from cheating. Don't expect to earn a lot of money on running a Lightning Network node right now.
And confirm me please is it accept BitPay?
BitPay does not accept Lightning Network payments. Introducing SegWit addresses and fixing their QR codes will be huge milestones for them.
Hahaha. That would be their greatest development as a Bitcoin service. But have you used Bitpay? It now markets for Bitcoin Cash. But in a subtle/naughty way.
Plus criticizing Lightning is OK, but saying gift cards are more superior is the dumbest way to criticize it.
