My last assumption on BTCUSD was that it is in a wave 4 (primary) correction.
For that assumption to be true the target 653 and 590 must not be broken.
As it turns out, they were broken down very decisively, this is a good clean signal hinting at a major wave 2 correction instead. ( Which I've also mentioned in my list of possibilities)
These are the new targets to look out for, the first being the target for a primary wave 2 in case that isn't over yet (not very likely , and is already touched and broken once though it still hold in OHLC4 chart)
The last two at 61.8 and 78.6% retracement marks the correction targets for major wave 2 correction.
Trade with care.
