The knowledge you have few years back can't be matched with what you know today.
Imagine the (unknown) mistakes you have made few years back coming back to hunt you today.
After it happened you will be asking yourself, but I am a better person today, I know things better today, why me?
Your long time crypto wallet that you started this crypto journey with could not be safe any longer, why?
You could have approved some free DeFi claims on your wallet.
You could have given access or permissions on your wallet without you knowing.
Funny enough your funds that you have on the wallet can still be there till date, it doesn't mean that your funds are safe.
To be safer I suggest you create a newer wallet and abandon your old ways of been a bit reckless.
This time no more permissions granted on a crypto wallet that you want to use to store your coins for a long term, if you are a fan of Airdrops, have a separate wallet for that and don't keep any assets on such wallet.

Dude, even Vitalik had his privatekeys printed out to offline papers for his bags, and that string of letters and numbers were divided to several physical locations (one of them being kept by his parents). You think he couldn't afford to buy a hardware wallet?
Separate wallets for different things is a good idea, but you might be adding up some extra level difficulty for yourself when it comes to filling your taxes when you need to keep track on what's coming from where and you have 100+ wallets. It's not hard if you have a plan for it though.
