I don't think you should be too worried. I think we'll remember the summer of 2012 as the time when the amateurs got washed out. There was clearly going to be a time when the price of a bitcoin grew to the point where it attracted a lot of black hat attention. That time is now :-). There professionals are moving in, both new services, bitinstant for example, and the older services that have been dinged but grew up fast and solidified their operations (Gox for example).
Also, WRT upward pressure you only mention bitcoin related items. But do not forget the larger economic situation, in the forefront right now the Euro and the other PIIGS. The Greece situation will come back to the front pages short-medium term. And long term, many other countries USA Germany are very bad WRT debt as well.
Also, Bitcoin really saves $ as an international currency, and so the increased trade volumes in Asia, especially in btcchina, is very interesting. Because when buyers in the USA meet the suppliers in China and BOTH already use bitcoin we'll get rapid escalation of BTC velocity (1-2 years out). And the savings will force others in these extremely competitive low margin marketplaces to adopt bitcoin or lose sales.
