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.
$2000+ is possible only if that scaling debate ends in a good way.(tbh i don't know what way it is. But i certainly know i only trust bitcoin core, not anything else) If not, we'll be crawling around 1k$ for a very long time. The support below 1k$ is very strong yet it doesn't matter how strong it is if the problems don't get solved. We are losing the market dominance to altcoins. That's a bigger problem than bitcoin's price.
