I believe Bitcoin's stability is crucial for various reasons, with the most important being its role in establishing trust and legitimacy in the industry. This stability is key for attracting new investors, fostering wider adoption, enhancing long-term value, and supporting sustainable growth.
Without the stability provided by Bitcoin (or a similar coin), confidence among traders would be lacking, and I don’t believe the crypto industry would be as popular as it is today. At least, that's my take on it. Having at least one stable resource is essential. Personally, I recommend a 70-30 split between Bitcoin and Altcoins, depending on market conditions.
