BTC dominance & sentiment
The contest gives you four markets — BTC, ETH, SOL and XRP — and they do not move independently. Understanding how they move together is worth more than any indicator applied to one of them alone.
Bitcoin is the market's tide
BTC dominance is Bitcoin's share of total crypto market capitalisation. Its direction describes where risk appetite sits within crypto:
- Dominance rising — capital sheltering in the biggest asset. Typical in fear phases and early recoveries. Alts underperform BTC even when green.
- Dominance falling while BTC is stable/rising — confidence spilling outward; the classic "alt season" pattern where ETH, then large caps like SOL and XRP, outrun Bitcoin.
- Everything falling — in a real deleveraging, correlations go to one and dominance detail stops mattering; only position size protects you.
Altcoin beta — the practical consequence
SOL and XRP typically behave like leveraged expressions of Bitcoin's direction: when BTC moves 3%, they routinely move 5–8% the same way. That "beta" cuts both ways and interacts dangerously with leverage — 10x on SOL during a BTC-driven move is effectively more market exposure than 10x on BTC itself. Two practical rules follow: check the BTC chart before trading any alt, because your alt trade is mostly a BTC trade with amplification; and remember that "hedging" a BTC long with a SOL short doubles your margin usage while still leaving you exposed to the pair's changing relationship.
The Fear & Greed index
The crypto Fear & Greed index compresses several inputs — volatility, momentum, social-media activity, dominance, search trends — into a 0 (extreme fear) to 100 (extreme greed) reading. Its value is contrarian and only at the extremes: single-digit fear has historically clustered near durable lows, and sustained 85+ greed near tops. Between roughly 20 and 80 it is weather, not signal.
Sentiment gauges are slow, composite, and occasionally simply wrong; nothing about "extreme fear" prevents fear from getting more extreme. Treat the index like funding extremes — a warning that a trade is crowded, never a trigger by itself. Confirm with structure: a sweep-and-reclaim of a major low during extreme fear is a signal; the number alone is a mood ring.
Trade the four contest markets as one correlated system: BTC sets the tide, dominance tells you which way capital is rotating, alt beta amplifies everything, and sentiment extremes mark the moments when the crowd is most likely wrong.
