It doesn't happen very often that the headlines about Bitfinex are positive for them and the rest of the ecosystem, but this time it's different.
It really sucks that there are plenty of exchanges still not allowing their traders to withdraw to bc1 addresses. I hope that this will motivate other exchanges to follow the same path.
According to an exchange of Tweets between CZ and a Bitcoiner earlier this month, CZ has indicated to roll out support for Segwit before the end of the year. Not sure how serious he is here, but it would provide a massive boost for Segwit's adoption. Lets hope for the best.
This is a good move from bitfinex, hope they would also remove the deposit fees they are asking for. I've always found that deposit fee useless.
Traders generally look for low fees, if many of exchanges also support native segwit, it would increase capital flow between exchanges resulting into stabler market.
