... we all expect bitcoin will more likely go up, than down don't we?
No, no one knows what will happen to BTC tomorrow. Past history is not an indication of future performance.
When you paid for your order, you converted BTC to bASICs, and the BTC/bASIC exchange rate has changed since. So has the BTC/USD rate, although the USD/bASIC rate hasn't changed. I think that's the most reasonable way to look at it.
