Investing in Bitcoin has changed over the years. Initially, buying a whole Bitcoin or even a thousand at a low cost was possible. Now, with the higher price, fractional buying and Dollar-Cost Averaging (DCA) are popular strategies. Believers anticipate Bitcoin's eventual surge, making any entry point valid. However, corrections do occur, providing opportunities to add to holdings and sell for profit during upward trends. It's essential to adapt strategies based on market conditions and believe in Bitcoin's long-term growth potential.
