I am an absolute noob when it comes to bitcoin, I just bought a small amount back then and decided to hold and see how high it went.

I think no one can disagree that hardware wallets are the way to go but... AFAIK, old blockchain.info wallets are not that easy to recover. Don't you need the wallet backup and also a couple of passwords to recover it? That would be mean that whoever gained access to the wallet might have got it through you, meaning, you should probably consider wiping your computer in case your wallet credentials were stored there.
information such as keys,seeds etc. to have access on your wallet and this is the pain when you do really entrust up on it fully and once updates and changes been applied then
it would really be a challenge on retreiving those back but i do read up that there's a way on getting those or accessing the coins but as mentioned that those coins
had already been wiped or stole out which simply means that keys or account log in or credentials had been exposed.
