While it is unclear if it was the lack of miners on the ETH network for the Constantinople to fail, but certainly it is of great interest to miners. Why? Because this upgrade would lower the reward for the miners, and instead of getting 3 ETH, they will get only 2 ETH as a block reward. However, at the same time, Constantinople should reduce the rate, which makes it more attractive for investors.
While the update failed, investors didn’t seem to have any reaction as price remained within a very narrow range; between btc 0.031 support and 0.032 resistance. Both of these are the level, and its clear how the 38.2% level is currently acting as the resistance. Although, looking at he 61.8% Fibs support, it was broken on the 11 October, and later, on the 15 October it was rejected.
There is an impression that market is going through the uncertainty, as ETH/BTC price struggling to establish a clear direction during the past 3 days. Yes, it spiked up on the 15 October, reaching the btc 0.0344 high. However, the 88.6% Fibs support, 200 Moving Average and the long-term downtrend were rejected, and the 4h closing price below the btc 0.032 resistance.
As the downside risk is very high, price might decline further, reaching either btc 0.0292, 0.0281, 0.0271 support. Nevertheless, for this to happen, 4h close must be below the btc 0.03 psychological support. On the upside, close above the btc 0.032 might be considered as a buy signal for short-term investors, and ETH/BTC should re-test the btc 0.034 resistance.
