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.
Clarification,
they are instant (only on LN offchain network, redemption on the onchain Bitcoin network is controlled by preset time locks)
and cost way less than on-chain transactions.
(This is dependent on the number of transactions made,
make a single transaction on LN and you paid more than a single onchain bitcoin transaction.
You have to make multiple transactions to the exact same person to save the most on fees.)
ie: Gift Cards have proven superior over Lightning Network for actually removing transactions offchain

Quote from: Khaos77
The above brings an interesting development, LN users that don't consciously plan their transactions to maximize offchain transaction over onchain transactions could actually generate more onchain transactions than if they paid directly onchain and potentially nullify any transactions reduction that LN could have provided.
