I've only used Kraken so can't compare to others but I've been happy with their service.
All good, seems they suddenly figured out to verify my account
Took 1 week and here is the reply:
Your Kraken account is verified to Tier 3.
Tier 3 allows you to deposit or withdraw cash through your bank and gives you higher funding limits.
The daily/monthly funding limit for cash is $25,000/$200,000 (USD equivalent). Before depositing from your bank, always check your funding limits to make sure the deposit doesn't take you over your limits. The daily/monthly withdrawal limit for digital currency is $50,000/$200,000 (USD equivalent). There is no digital currency deposit limit.
Here are some important reminders about bank deposits: 1) The name on the bank account must match the name on your Kraken account (we don't accept 3rd party deposits); 2) Multiple deposits of the same amounts within a few days of each other may be delayed; 3) Include your reference code with the deposit, which is your public account ID followed by 'kraken.com'.
If you need higher funding limits, you need a Tier 4 account. If you are interested in a personal or corporate Tier 4 account, please contact us through support:
Click 'Submit a request,' and choose the category "Verification (Tier 4)" for your request.
So that means go ahead trading now.
did you ever figured out if that was possible or if it is possible to transfer USD from kraken to any other EMI like mister tango or transferwise?
