Market analysis: 3 signals of a speculative bubble in crypto

Parabolic Movement: When Price Charts Defy Gravity
Experienced crypto traders know it well: a price chart adopting a parabolic shape represents one of the most reliable signals of a forming bubble. This phenomenon is characterized by an exponential acceleration in price over a short period, creating a trajectory that visually resembles a mathematical parabola.
Bitcoin has experienced several of these phases throughout its history. In 2017, BTC surged from $1,000 to nearly $20,000 in less than a year, before correcting by 80%. More recently, certain altcoins have posted gains of 500% in just a few weeks, followed by equally spectacular crashes. This pattern repeats systematically: euphoria drives prices to unsustainable levels, then reality reasserts itself.

The difficulty lies in the timing. Identifying a parabolic movement doesn’t guarantee being able to exit at the top. Markets can remain irrational longer than you can remain solvent, as Keynes famously said. Technical analysis must therefore be accompanied by rigorous risk management and predefined take-profit levels.
Extreme Volatility and Volume: Two Contradictory Indicators
High volatility represents both the charm and danger of cryptocurrencies. During speculative bubble phases, daily oscillations can reach 20 to 30%, creating opportunities for rapid gains, but also liquidation risks for leveraged positions.
A particularly revealing phenomenon occurs when volatility increases while trading volume decreases. This divergence generally signals an exhaustion of bullish momentum. Buyers become scarce, sell orders accumulate, and the slightest negative event can trigger a cascade of liquidations. Whales and institutions closely monitor these metrics to anticipate trend reversals.
Indicators like Average True Range (ATR) or Bollinger Bands allow for quantifying this volatility. When these bands widen excessively, it often indicates that a peak is near. Volume confirmed by tools like the On-Balance Volume (OBV) indicator provides essential complementary reading to validate or invalidate price signals.
FOMO: The Psychological Catalyst of Crypto Bubbles
The fear of missing out (FOMO) represents the emotional fuel of speculative bubbles. This cognitive bias drives retail investors to buy at the highs, precisely when smart money begins taking profits.
Social media considerably amplifies this phenomenon. A viral tweet, a promising YouTube video, or a thread on X is enough to trigger a wave of impulsive buying. New entrants, attracted by gains displayed by others, enter the market without prior analysis or exit strategy. This dynamic creates artificial demand that inflates prices beyond any rational valuation.
Intense FOMO phases are easily recognizable: explosion of Google searches for crypto terms, multiplication of account openings on exchanges, and discussions dominated by gains rather than fundamental analysis. These sociometric signals, combined with technical indicators, offer a holistic view of market conditions and allow anticipation of major reversals.
