Data from Cointelegraph Markets Pro and TradingView showed BTC/USD maintaining newly re-won ground Saturday, with the pair's correlation to stock makets firmly in focus.

Amid the newfound strength, the mood was conspicuously more buoyant than in recent days or even weeks.

Popular analyst Credible Crypto compared current action to Q4 2020, in which Bitcoin challenged $12,000 prior to breaking three-year all-time highs.
