John Bollinger hints at an impending crypto outbreak

Technical analyst John Bollinger says Ethereum and Solana are showing bullish “W” bottom patterns and hinted that a similar setup on the Bitcoin chart could indicate a big move for the crypto market.

The “W” bottom is a bullish reversal signal that often precedes sharp upward moves. Bollinger, who invented the Bollinger Bands volatility indicator, said the formation has yet to appear on the Bitcoin chart, telling his 254,000 followers in a X message that “it will soon be time to pay attention.”

The pseudonymous trader and analyst ‘Satoshi Flipper’ noted in an X-post that the last time Bollinger told his followers to pay attention was in July 2024, when Bitcoin skyrocketed from $49,000 to $110,000.

ETH and SOL recover from weekly losses, while Bitcoin starts to rise

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 recovered modestly from recent losses, while on-chain data from Santiment suggests that Bitcoin, ETH and XRP are now in undervalued territory, a situation that has historically preceded market recoveries.

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

But Bitcoin remains more than 4% in the red even after rising 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 offer buying opportunities

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

In an October 17 post on

📉 With the past week of crypto’s carnage, the MVRV (Mean Value to Realized Value) of top caps has jumped into negative range. The average returns of wallets active over the past 30 days imply that (especially) a recovery for XRP is likely:

The MVRV is an important on-chain metric used to evaluate whether a crypto is overvalued or undervalued relative to its historical cost base.

The ‘MV’, or market value, represents the current market capitalization of a crypto, i.e. the supply multiplied by the price.

Meanwhile, the “RV,” or realized value, is the total of all coins based on the price at which they last moved up the chain, which reflects 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 a profit. Conversely, a figure below 1% shows that holders are making a loss.

According to Santiment, these MVRV measurements suggest that a market recovery is approaching.
