Sorry for my English, but I think all you need to know what risk you must meet to use moneybookers.
Please read what happened to me with moneybookers.
They closed my account, deleting the last transactions creandomi massive damage. I recommend you not use it for both btc than as a traditional method of payment. Moneybookers has to close, are not at all serious.
