Personally when you want to invest in altcoins, first decide whether you are going to be gunning for long-term or short-term gains. That would mean coins that are established with strong fundamentals and growth, like Ethereum (ETH) or BTC, for the long term, and when it comes to short-term investments, I'll suggest to turn your focus to recently outperforming funds or those in the emerging decentralized finance or NFT sectors, but i should warned you that you need to be careful with their high volatility. Going into tier-one and moving forward to innovative businesses that can grow while managing risk through detailed analysis is key and you need a lot of patience. There's a lot of community that you can join and that's advisable to keep up to date with the market trends and innovations to keep well-rounded decision-making when its time to bullrun. I hope my suggestion will help you create a better investment strategy by balancing the portfolio and monitoring cryptocurrency market dynamics.
