Deciding between buying Bitcoin or altcoins depends on your goals and risk level. Bitcoin, as a stable and widely accepted asset, is generally considered safer for long-term investing. Altcoins, on the other hand, can provide large percentage gains, but they are also more subject to volatility.
If your goal is investing for long-term growth with minimal risk, Bitcoin may be preferable. If you are willing to take more risk and are looking for short-term profit opportunities, altcoins may be of interest.
