For Ethereum, which returned from the $ 2100 resistance in the short term, a Gann Fan fit appears in the long term. If Ethereum, which is in the descending channel, holds at $ 1640, which is the Gann Fan support, it can walk to the descending channel resistance, and from there to the Gann Fan resistance. If it cannot hold the $1640 level, the target will be 1365.
