Is it still worth buying Cardano?

Excuse me, I'm a bit perplexed about the current cryptocurrency market. I've been hearing a lot about Cardano and its potential, but with the volatile nature of this industry, I'm not quite sure if it's still worth investing in. Could you please shed some light on this matter? I'd appreciate it if you could provide me with an insight into Cardano's current performance, its future prospects, and maybe some comparison with other prominent cryptocurrencies. Is Cardano still a solid choice for my portfolio, or should I look elsewhere? Thank you in advance for your valuable advice.
