Indicator Check · Bitcoin and Ethereum since 2017

Golden cross, RSI & co.: what popular crypto signals are really worth

We recalculated 10 popular signals for Bitcoin and Ethereum since 2017 – with rules fixed before the first calculation. Most had no measurable edge, one did.

Showed an edge

Below the 200-week line for Ethereum: 90 days later, on average +30 percentage points versus normal (10 signals).

With 20 tests, a hit can also be chance.

Tendency, not confirmed

Golden cross

On average in the claimed direction and fairly consistent – but not enough to count as proof.

Tended to go the other way

Extreme fear for Bitcoin and Ethereum even tended to work the other way round: afterwards the price did worse than normal.

No clear edge

Death crossRSI oversoldRSI overboughtExtreme greedMayer Multiple low

On their own, these signals had no measurable advantage over normal performance.

Too rare for a verdict: Mayer Multiple high, Below the 200-week line (Bitcoin), and Pi Cycle Top.

What helps instead

We fixed the rules on 30 Sep 2026, before calculating a single result. The comparison is always with normal performance over the same period – not with zero. This is not investment advice.

How we calculate

  • Daily closes from Binance from 08/17/2017, Fear & Greed Index: alternative.me from 02/01/2018. Longer Bitcoin histories from other exchanges can only be used commercially with a separate licence – which is why the years before 2017 are missing.
  • A signal counts on the day the condition becomes true. Further signals of the same kind in the following 30 days don't count.
  • We compare the return after 30, 90 and 180 days with the normal return over the same span – on all days on which the indicator could be calculated.
  • Verdict over 90 days: fewer than 8 signals = “too few signals”, a t-value of 2 or more in the claimed direction = “edge measured”, 1 or more = “tendency, not confirmed”, otherwise “no clear edge”. For warning signals, the edge is how much weaker the price ran than normal.
  • Limits: signals can overlap over 90 and 180 days – the t-value then overstates the certainty. The data covers roughly two market cycles. Hypothetical, retrospective, no fees.
