It's possible that they have high load now. I was using OKpay for some weeks and deposits were creditied after 1-2 days. Now they take up to a week. I had to contact support for one recent deposit, but they resolved the problem in less than a day.

We'll see $100 again, but not now. For now, Bitcoin is solid and should be stable over 500$. The problem will be, when other better coin arrives. But for the next 2-3 years I see not a real competitor. A new coin will have to mature until it succeeds, build a network, etc.
