I do not have technical knowledge, but I understand that sooner or later there comes a time when things need to be improved. And in bitcoin, too, there are imperfections. And it seems that people have learned from the updates to make profit...
I personally have lack of knowledge about segwet2, but i can expect that everything will be in favour of bitocin. as bitcoin is the first crypto currency and most of the people have more trust on it, therefore we can expect that bitcoin will remain as the number one crypto currency of the world for a long long time. Hope that segwet2 will be in faovour of bitcoin.
