Is Polkadot good long term?

I've been following the crypto scene for a while, and I've been eyeing Polkadot with a keen interest. I'm wondering, is Polkadot really a good investment for the long term? I've heard about its interoperability features and how it aims to connect different blockchains, but is that enough to justify a long-term hold? The crypto market is so volatile, and I don't want to make a mistake by investing in something that might not pan out in the end. Could you give me some insights on Polkadot's potential for the future? I'd really appreciate it.
