I think coinbase is asking for fee's for every transaction right now because of the miners fee increase .. i just send some few bitcoins in other wallet yesterday and they are asking for miners fee.. unlike before that they don't even asking for transaction fee.
For xapo. i have problem with xapo i can't login with my account even my pin is correct by always try again to confirm the verification..
I think only here in my country has no fee for every transaction which is coins.ph. and i think they will change this rule in the future because of the miners fee increased.
