Bitcoin is currently sitting at both the 61.8% and the off major levels, as well as a on the 4 hour
4 Hour Divergence:
These are all good signs, I would consider this a good long entry point, be aware that further downside is still possible, failure to get a reversal going at these levels could signal a move lower to potentially the $34,000 - $38,000 USD, at which point, all other things being equal would represent A GREAT ENTRY POINT.
P.S. Bitcoin appears to be following the move lower I forecast several weeks ago, I recommend you give it read.
