As a consequence, I was locked-out of my BITFINEX account as well as of my BITSO account.
It took 6 minutes to put this new IP address on the BITSO whitelist, however my ticket to BITFINEX helpdesk is now 30 hrs old and no reply yet!
This is totally unacceptable, and the worst "customer service" I have ever experienced in 1 year of trading!!!
Why are you using an IP whitelist? Too many things can go wrong. If your router dies and needs to be replaced, this will change your IP address. With options like UDP and TOTP authorization in addition to email authentication, I just don't see the value in IP whitelisting.
With some exchanges like BTC-e, I've seen people locked out for weeks over this (if they could even manage to get through to support). I can't comment on Bitfinex, personally. I left after the hack last year and never returned.
Maybe they have a bad support, but they are the only exchange that is online that is never going to steal your money
After their reaction to Bitfinex'd and the community concerns over Tether, I'm more wary of this exchange by the day. Instead of providing the audits we all want to see, they continue to evade and are now threatening critics with lawsuits. That comes off very shady.
I also lost money in the hack last year, and I certainly don't feel I was "repaid" by their debt token scheme....
