This is hard to predict what the cap will be this year. With all the issues now in the cryptocurrency market it is hard to say one way or the other if this coin can survive, flourish, and be regulated like it should be. From what I've seen this is a booming market and there are tons of new options available and new companies spring up lately. However, how stable are these companies? Can you really trust your investment in a currency that is hard to use, hard to cash out from, and have no regulatory control?
Have you ever tried to transfer this electronic currency to your bank account? If you have, you'd know the payment processing fees alone are extremely high and it is extremely difficult to make these transactions.
What good is money that you can't spend in a store? No store I know of will allow you to spend Bitcoins there and I know for a fact there are no Bitcoin debit cards.
Until some laws are set in motion, it is easier to access, spend, and transfer this currency, I don't think I'd get too excited one way or the other about the cap. There are some who pulled out at the right time when the Bitcoin had risen so much. Now people who invested and didn't pull out have lost money. The lower value is good for us, but will it continue to drop or can it make a comeback and rise again? I think that is the most important question to ask right now.
