Want to care a guess at a support bottom for this year? My educated guess is ~$1800 trading bottom, with a possible quick spike down to the ~$1500 range or so.
I don't dare predict bottoms before they happen.
I have made a realization, however. The bear market is likely to continue until at least February 2018 because that's when the 2 MB hard fork is supposed to happen. Currently, the debate is a little subdued because everyone is fine with getting Segwit. It's the path afterward where the civil war will break out for earnest. Until that is resolved, I cannot imagine mid/long term bullish conditions.
