According to an analysis report by asset management company Grayscale, fundamental changes in Bitcoin's supply and demand balance may have a greater impact on the price of cryptocurrencies, especially the upcoming halving event. Historically, a period of price increase usually follows a halving event. However, a new factor (i.e., ETF) will also affect Bitcoin's performance in this year's April halving event. The report points out: "In addition to the overall positive on-chain fundamentals, Bitcoin’s market structure is favorable for prices after the halving." After each block mining reward is reduced to 3.125 Bitcoins post-halving, miners typically sell more of their Bitcoin inventory to cope with cost pressures, thereby increasing supply and lowering prices.
