Thank you very much, MintDice. I'm going to try the cold storage in a paper, because as you said, is the safest method. Thanks!
Make sure to keep the paper safe, you can try to laminate it or put it inside a lockbox.
Other ways to prevent it is by making a few copies of your Paper Wallet and keep it in a different places.
Do your research and understand how Paper Wallet works and see whether it fits your requirements as paper wallets are usually used for long term storage
If you're spending your coins regulary, it'd be better to get desktop based wallet.
Yep, paper wallet is probably the safest option, but it's not convenient if you need to send your coins often. If you are planning to HODL, it's ok.
You also can use combination of paper and desktop wallet. Keep biggest part of your coins on a paper wallet and also smaller part of BTC/Altcoin on a desktop wallet for your daily needs.
Also, hardware wallet can be a good option if you have some spare money to purchase it. And to avoid risks, buy only from official website or official retailer.
