One of the strongest long term signals for crypto just fired. Buy. Mining rate is recovering after the China crackdown. Newer, more green, miners taking over, ready for the next leg of growth.
The hash ribbon signal is useless for ETH. It has been designed only with BTC in mind and doesn't work with any other coin. You had the buy signal on the 17'th of May and what happened then? It went from 3.5k to 1.9k in one day.
