Don’t trust altcoins in the market as they can’t be trustable and stay valuable for long. Most of them are just too good to be true at first and after seeing some crashes in the market, eventually altcoins have start to lose their value and end us shitcoins. Instead, focus and prioritize bitcoin. Bitcoin has been the most trusted crypto in the market, you will never go wrong with it.
Not all altcoins are bad, there are some altcoins can be trusted. There is nothing wrong to trust the top altcoins such as ETH, ADA, BNB, XRP, SOL, TRX, MATIC, DOT, or XLM. As long as the altcoins have good fundamentals or they have great developers/owners, we can believe that the altcoins can survive a long time. We just avoid to invest in shitcoins, meme coins, or the new coins that have weak fundamentals/no fundamentals. Those altcoins which only rely on the hype are better to avoid.
Sure, the safest coin to invest for the long holding, Bitcoin is the best choice. Everyone must have Bitcoin in their crypto assets, it should be the main asset for holding. As Bitcoin is the king of crypto coin, it always deserves to be prioritized. However, I'm sure many people won't miss the chance to take high profits on good altcoins as well.
