John Bollinger hints at an impending crypto breakout

Technical analyst John Bollinger claims that Ethereum and Solana are showing bullish “W” bottom patterns and hinted that a similar pattern on Bitcoin’s chart could indicate a significant move for the crypto market.

The “W” bottom is a bullish reversal signal that often precedes sharp bullish movements. Bollinger, who invented the Bollinger Bands Volatility Indicator, said the formation had not yet appeared on Bitcoin’s chart and told his 254,000 followers in an X-post that it was “almost time to pay attention.”

ETH and SOL recover from weekly losses, while Bitcoin begins to climb

Bollinger’s comments follow a volatile month for crypto, with a record $19 billion in liquidations on October 10 after US President Donald Trump announced additional 100% tariffs on Chinese exports.

Ethereum and Solana have since rebounded slightly from recent losses, while on-chain data from Santiment suggests that Bitcoin, ETH and XRP are now in undervalued territory, a setup that has historically preceded market recoveries.

Data from CoinMarketCap shows that the price of SOL has increased by 3% over the past week, while that of ETH has increased by more than 2%.

But Bitcoin remains more than 4% in the red even after climbing a fraction of a percent over the past 24 hours to trade at $107,080.07 as of 1 a.m. EST.

BTC, XRP and ETH present buying opportunities

While Bollinger urges traders and analysts to pay attention to crypto markets for a possible big move, on-chain intelligence and sentiment platform Santiment says several cryptos have recently dipped into undervalued territory.

📉 With last week’s bloodbath in cryptocurrencies, the MVRV (Mean Value to Realized Value) of top caps has moved into a negative range. The average returns of active portfolios over the past 30 days imply that a recovery in XRP (in particular) is likely:

MVRV is a key on-chain metric used to assess whether a crypto is overvalued or undervalued relative to its historical cost.

“MV,” or market value, represents the current market capitalization of a crypto, which is its supply multiplied by its price.

Meanwhile, the “RV,” or realized value, is the aggregate of all coins based on the price at which they last moved on the chain, reflecting the realized cost basis of all holders.

Santiment said in his post that the MVRV for Bitcoin is around -5.8%. The indicator also stands at -8.4% for Ethereum. The platform then highlighted XRP for its MVRV of -15.3%.

An MVRV above 1% suggests that holders are making profits. Conversely, a reading below 1% shows that holders are lost.

According to Santiment, these MVRV readings suggest that a market rebound is approaching.
