segwit is now ++2 years old :-) any bitcoin client which is younger then 2 Years,
or was updated in past 2 years is able to work with the segwit address layout :-)
if its your own bitcoin client , then hurry up and update your wallet,
if its an external service provider he should hurry up and update his client
Your right. I used Doge to make the deposit. I thought the Jaxx Wallet was Segwit enabled, it's not, that was news to me. I like the Unamed Exchange. There were a couple of OGs in the Trollbox, had a good chat.
