So basically TL:DR, you think it'll be 2500-3500. Meh, that's too high. That's if everything goes perfectly which it is not at the moment. I guess 1800 by the end of 2017 assuming all of the block size issues are finally resolved by someone.
Yeah assuming the BTU thing gets solved and BTC gets back to business as usual, then think 1500+ price is at least garmented by the end of year probably sooner. But if hard fork happens we all know what condition BTC will be in probably even going below $500.
