Except that if I want to save a considerable amount of money, but in bitcoins.
there are hardware wallets you should check them as they are the safest
yes, these are the safest and simplest. not the cheapest though. the cheapest is paper wallets, but keep in mind your printer will keep the files in it and this can be hacked. there are steps to making paper wallets hacker-proof, but it is a bit of work and knowledge needed. since you are IT you will be able to figure it out.
i am assuming English is not your native tongue. i am sure you can find the information to create safest paper wallets in your language, possibly in the non-english parts of this forum.
if you do plan to collect a large amount of btc, I would invest in a hardware wallet. there are good ones as cheap as 35$ USD, they are simple to set up and use and you need not worry about collecting a large amount of paper, plus you can spend and save with it just like any other wallet, without the risk of being hacked. I use a ledger wallet and I am very happy with its ease and security.
welcome and good luck
