I think segwit will not be able to happen with bitcoin, the request rate is too high, it is almost impossible for bitcoin. LTC is only 75%, so it's easy to achieve and will soon grow. For bitcoin, the head of the second largest lake in China has stated that bitcoins do not need segwit, which is a very hard affirmation of the heads, they assert that the bitcoin is strong enough to grow freely. And it does not need any impact. I personally feel that is true, and I believe segwit will not happen to bitcoin.
