Issue with Crypto Exchanges

Watching lots of videos on YT and seeing issues with Binance, should I get a cold storage?

I'm with Coinbase and have 0.5 BTC (I know, I shoudn't mention this), but I need advise. - I also have other coins...

I plan to hold 80% of my assets until March 2025.

Should I get a cold storage?

I don't even know how it works, I've looked online for something like this:

Sorry, I'm really new to this, so please respect and give solid advice.

Thank you!
