Bitcoin

(Bitstamp:BTCUSD 4h)

Bitcoin has seen the anticipated drop through $9222 on very high volume and is moving to test historical support levels. The first level to watch is the $8575, which marks the 78.6% retracement of the macro bull run between $5555 and $19666. We may see a bit of a pullback here, but the target I am watching comes at $7888.

(Bitstamp:BTCUSD Daily)

Historically, Bitcoin has a habit of retracing to around the level of its previous high after each leg up. Therefore $7888, being the previous high, makes a logical target region for this move.
We'll have to keep a close eye on the reaction to this support level, as a strong break downwards here would be a sign of a longer term bear market.
And, if you're on the bullish side, I would recommend waiting for a strong bullish confirmation before undertaking any positions, as this market is looking a lot weaker than it did in 2017.

(Bitstamp:BTCUSD 30m)

All that being said, in the short term we do see some bullish divergence on both the RSI and MACD, suggesting that we will likely see a bit of a bounce in the near future.
The bounce will likely form a bearish consolidation pattern, but we'll have to wait and see.

Ethereum

(Bitstamp:ETHUSD 4h)

Ethereum is following suit and has broken through the $1000 and $984 supports. It will likely continue falling until Bitcoin finds a support for this leg down. The next supports come at $905 from the last drop and $870 as the high of the previous bull run.
Generally, Ethereum has been looking stronger than Bitcoin, with steeper retraces after bearish moves and shorter legs down, so we may well see a decoupling from BTCUSD at a major support level. I would still always recommend waiting for a strong bullish reversal signal first though.

(Bitstamp:ETHBTC 4h)

We can see how the ETHBTC ratio is moving strongly counter-trend to BTCUSD (pink line), backing up the strength of Ethereum, especially considering that ETHBTC would historically follow BTCUSD reversals.
The bull run that I commented on yesterday managed to outdo all expectations, blasting straight through the target price of 0.1141 to reach as high as 0.1234. But that appears to be coming at the cost of a heavy correction afterwards, which is now moving to test the 61.8% support.
As with ETHUSD, I would recommend waiting for a confirmed support zone before building up any long positions.

Bitcoin Cash

(Poloniex:BCHBTC 4h)

BCHBTC managed to break down from the suspected consolidation zone and through the 0.1420 support (following in BTCUSD's drop), and is now moving to retest the major support at 0.1366.
This highlights why I always recommend waiting for confirmations before entering positions, especially after so much bearish movement.
We'll have to watch for how Bitcoin Cash reacts to the 0.1366 support, but at the moment things are looking very bearish.

NEO

(Bitfinex:NEOBTC 4h)

Similarly to Bitcoin Cash, Neo has also broken downwards from the suspected bullish consolidation zone. This move has retested the 0.1351 support and so far looks to have made a strong rejection, which is a bullish sign.
I would recommend holding off for a few days to see if/ where we form support and how Neo will to BTCUSD's movement.

Cardano

(Bittrex:ADABTC 4h)

ADABTC too has followed Bitcoin and broken downwards. It saw a strong break of the 4730 support, triggering the stop for the suggested position. As with the others, I would recommend holding off for a little while and to watch for the formation of a support zone and see how we react to the continued movement of BTCUSD.
