Wex is clearly having some back-end issues, and I suspect they are fixing them behind closed doors while communicating maintenance to keep everyone calm, this has always been Wex/BTC-E's way of communications when issues arrised, this time it's accompanied with a price-spike which adds to the fear of us users that things are going really wrong.
I can't give you guys any advice on keeping funds online or withdrawing through the withdrawable cryptos, but I personally keep my funds, which are significant, on the exchange, due to my believe everything will be sorted out in a week or so.
Money is made during times of crysis when there is fear and blood on the street, there are chances for opportunists now who are able to invest some money they can miss and are willing to take a calculated risk.
nothing wrong with some calculated risk---that's what makes markets. just be sure to spread the risk around. i was far too exposed to BTC-E when it went down in 2017 and will never make that mistake again.
these days, i'm so paranoid about exchange exit scams, etc that i keep the vast majority of funds in BTC (offline) and keep a stack for high-leverage hedging (mostly futures).
good luck out there, i'm really hoping for a positive outcome at WEX here. as much as i lost on BTC-E last year, i still have a place in my heart for the admins and the people who trade there. lots of money made there over years, and lots of good times in the trollbox.
