I tried to withdraw the paid for Bitcoins - but MtGox (suspecting this to be a fraudulent transaction), put a 30-day waiting period on my purchased Bitcoin - before withdrawal can be effected. 

Are my paid-for purchased items considered delivered, if I cannot withdraw them immediately, and they are not in my full control?  Is it some 30-day fixed deposit without interest?

Before the MtGox Paypal account freeze (due to chargebacks of fraudulent stolen credit card transactions on the MtGox Paypal account), I had a positive outlook of MtGox's future, and 30 days would be ok to wait. Currently however, I am hesitant and do not know what will happen with MtGox in the next few weeks?
