Just a simple question from me,
1. If I won't upgrade into the supporting SegWit and Will it give any impact for me to sending or receiving such amount from the Supporting SegWit?
Not upgrading to a segwit enabled wallet will not affect sending or receiving Bitcoin as you do now. The backwards compatibility of segwit means that you will be able to receive from someone with segwit (albeit after the transaction has confirmed a few times) and send to someone who wants to use segwit.
2. Why SegWit is complex rather than a simple hardfork.
Hard forks are far from simple. Segwit also solves a lot of problems simultaneously, not just capacity. A "simple" block size increase hard fork ignores a lot of the nuance that comes from making such a change
3. Are the implementing of SegWit will need blocksize hardfork?
Segwit does not need a block size increase hard fork.
The others were saying if Lightning Network was possible without SegWit and it is true? or SegWit was becoming a responsibility for Lightning Network.
Why bitcoin core has opted the complex softfork rather than be implemented into hardfork with more simply and cleaner.
