Major investors such as Marc Andreessen and Richard Branson have invested hundreds of millions of dollars in bitcoin startups, showing confidence in bitcoin's value. While some myths persist that bitcoin is only used for drugs or illegal activities, major companies like Microsoft, Dell, and Expedia accept bitcoin, with over $150 billion in combined annual revenue. Additionally, concerns that bitcoin was hacked or that altcoins could replace it are addressed, noting that the decentralized blockchain has remained secure since 2009 and bitcoin benefits from first mover advantage and widespread adoption over other cryptocurrencies.
