I sent a 5 figure amount via SEPA from Barclays (UK) after converting to Euros and that was deposited after 4 days.

Upon wiring a second similar amount I got a call from the bank to confirm and after a week of worrying I got a Know Your Customer email from Bitstamp:


We received your deposit transfer and in order to provide a high quality and reliable service when certain volume or frequency thresholds are met further KYC procedure is needed. We also kindly ask you to please help us better understand the nature of your use of our service by answering the following KYC questioner:
1. How did you learn about Bitcoin?
2. What is the purpose of your trading on Bitstamp?
3. What type of trading will be conducted? Buying/selling/both? Estimated trade volume per month?
4. Which bank are you using? Please provide the complete address and SWIFT code.
5. Estimated amount that you would be depositing/withdrawing to/from your Bitstamp account per month (in USD and BTC)?
6. What is the origin of the funds which you are depositing to your Bitstamp account? Please provide any financial documentation which can confirm the origin.

All to be expected but the delay has cost me dearly unless the price drops back, although most will be sold through localbitcoin at a set mark up.
