Bitcoin is nearing $100,000, recovering from a low of $17,000 after the FTX collapse. The rise is attributed to expectations of a more crypto-friendly regulatory environment under the incoming Trump administration. While some investors are optimistic, experts caution about the volatility and risks associated with cryptocurrency investments. Bitcoin's recent surge is also linked to the approval of spot bitcoin ETFs and the impact of mining on the environment, raising concerns about energy consumption and carbon emissions.
