Bitcoin (BTC) only needs one more key on-chain signal for a classic bull market to begin, analyst David Puell says. In a tweet on Dec. 17, the Puell Multiple creator argued that the stage is almost set for the end of the BTC price bear market.Puell: Bitcoin network activity “underwhelming”Despite many calling for new BTC/USD lows of $12,000 or less this cycle, not everyone is wholly bearish on the outlook for Bitcoin.For Puell, two essential on-chain phenomena necessary for BTC price recovery are already in evidence.Long-term holders (LTHs) are resisting the urge to sell despite Bitcoin being down over 70% from its last all-time high. At the same time, short-term “speculators” are feeling acute pain from recent price action. As Cointelegraph reported, these “tourists” are likely already mostly gone from the market.All that is missing, Puell believes, is a rise in network activity from all participants.“On-chain, three factors are needed for a bull: 1. Holding behavior from long-term investors. 2. Painful losses from short-term speculators. 3. Network activity across the board,” he summarized.“Personally seeing 1 and 2. 3 is still underwhelming.”He added that “favorable” macro conditions would aid the turnaround, as well as crypto becoming more resilient to “contagion” in the form of “exogenous and endogenous ‘swans.’”BTC/USD traded at around $16,700 at the time of writing, data from Cointelegraph Markets Pro and TradingView showed.BTC/USD 1-hour candle chart (Bitstamp).
