I have hope for the future, but I think it will take a long time before we see 1000 $ or more. What can make bitcoin price to rise that much?
-A Currency Crisis: Citizens of any country experiencing high inflation or currency devaluation have a strong incentive to look for alternatives to holding their wealth in fiat cash. Since the 2009 financial crisis most of the world has been going through a period of low inflation, however there is a significant probability in the medium term future that competitive devaluation by countries seeking to prop up exports, or out of inflationary currency crises in specific countries, could drive a new wave of users into Bitcoin.
-A Banking Crisis: Banking crises in both Cyprus and Greece appear to have been a driving factor behind minor price jumps in the past, as it highlights the possibility that keeping money in banking system may not be as safe as people think
-Major Integrations: If, a trusted brand such as Paypal, for example, were to add the option of keeping BTC in their wallets we would almost certainly see a big jump in the number of users and therefore the price. Although that particular example may not seem very likely, there are dozens of others which could have a similar effect.
-The Halving: In the summer of 2016 the number of new coins being generated will halve. If the same amount of money keeps flowing into Bitcoin then the price will have to rise, and could easily push back into four figures.
