https://alternative.me/crypto/Go down the page to the chart and click on "max". You will see that the current reading of 10 is about as low as it can go.
I would say from looking at the chart; a reading above 35 is a buy signal.
Now is the good time to buy while an opportunity comes when price decline. Our hope is in every dip of btc price, so don't let chances be gone, because this will give us an assurance to gain as soon market survives. Recently we're at below 35, then another entry level is surely a good start for those who haven't yet hold btc before last bullrun reached at $60k.
