In Bitcoin terms, a bull market is when investors sense upward momentum. Prices keep climbing, and optimism feeds more optimism—often leading to increased trading volume and speculative mania. During these times, projects and altcoins can also experience big rallies, riding Bitcoin’s coattails.

Bull runs can attract mainstream attention and new participants, but they can also breed unsustainable hype. Eventually, the market may correct or transition into a bear phase. Nonetheless, many in the Bitcoin community view bull markets as cyclical waves, with each upsurge bringing in fresh capital and greater public awareness.
