Congrats @sparkpool_eth once again for inaugurating Muir Glacier!

ETH/USD: technical picture

ETH/USD hit the intraday low at $128.40 and recovered to $129.40 by the time of writing. The initial resistance is created by psychologic $130.00 reinforced by SMA50 (Simple Moving Average) 1-hour and the middle line of 1-hour Bollinger Band. Once it is out of the way, the upside is likely to gain traction with the next focus on $131.30 (SMA100 1-hour) and $132.60 (the upper line of 1-hour Bollinger Band). December 31 high at $131.40 is likely to limit the sort-term recovery.

On the downside, the support comes at $128.70 (SMA200 1-hour) and $127.80 ( the lower line of 1-hour Bollinger Band) We will need to see a sustainable move below this handle for the bearish momentum to gain traction. The next bearish target is $125.00 and $122.50 ( December 27 low).
