I believe that many altcoins will die off due to week fundamentals, all the weak projects, meme coins and speculative tokens will vanish over time. Bitcoin is more entrenched than any other crypto that's why I believe that it's strength will make sure any crypto that actually survives, must justify its existence
The crypto market does not adopt the law of the jungle "the strong kill the weak", the market cycle is purely determined by demand, supply and the confidence of traders and investors. Bitcoin quality is unquestionable, everyone knows this coin is the King of Cryptocurrencies, but that doesn't mean it preys on weak coins.
There are several reasons why coins with weak fundamentals fail to survive in the market or even disappear from circulation. These are all due to lack of adoption, lack of features that attract investors, and security issues. Competition in the crypto market is very competitive, it needs to compete fiercely with other cryptos to gain interest from investors, regulatory changes also determine their fate, if these coins do not comply with established regulatory standards, then you need to think twice about investing in coins like this.
Bitcoin has stood on its own without needing help, support and without having to nudge other coins, so even if new coins are able to survive for a long time, their existence will never disturb Bitcoin position.
