I think bitcoin could well reach $2,000 - $3,000 if this $6,000 support get's broken.
It has proven to be wrong, although $6K walls broken last month, bitcoin holds pretty well so far, as the main attraction comes from the ETF files and be able to reach over $8K. The bitcoin market might react if a long-awaited ETF finally approved as there are 7 ETF files are waiting for SEC consideration.
And this is not a good year for crypto I believe. Late 2019 we'll see some action.
I'd say, we'll see some action by the end of this year, at least the price possibly reach $10K as the new resistance level.
