If the leading signal on the 4-hr MACD goes upwards through 0, I may take a gamble and buy. Slowly creeping upwards now.

Looking good, wedge broken.
Yet the problem is volume.
Anyway take a close look at ETHBTC / 1D , hammer on good volume yesterday (and close to historic support).
Bear in mind an altcoin rally can ignite a BTC rally, eventually.
Good luck.
