segwit as a technical solution is complete nonsense, there's so much material about it online, just research it. I want a proper protocol upgrade that does not introduce any additional technical debt. take flextrans for example, way better solution to the same problems segwit attempts to solve.
I know this argument. Has some validity, but I am being pragmatic ... we won't find consensus for an "ideal" solution with minimal technical debt and the absolutely perfect tech. Flextrans is indeed interesting, but it seems that it is an one-man project and would have needed more testing.
I mean BTC what threw away 35~40% market share in the process in 4 months. It's hard to think of any other comparable even even in tech.
Market cap is not the same than market share. I agree with you that the scaling war has done some danger to Bitcoin, but the altcoin rally was caused only in part by it - in part also by Ethereum's ICOs and simply awareness for cryptocurrencies that led to greedy speculation, above all in countries like Japan and South Korea.
