As the Bitcoin halving approaches next year, the cryptocurrency's market dominance has reached its highest level in two and a half years, currently standing at 54%. This is seen as a bullish indicator for Bitcoin, which has seen a nearly 30% gain in October alone, rising from $27,000 to $35,000. The halving event, which occurs every four years and cuts the mining reward per block in half, is expected to drive demand for Bitcoin upwards and bring about a bullish trend. With a fixed total supply of 21 million, the halving helps to counteract inflation and maintain scarcity.
