You just need to Google things, go to YouTube, stay away from Web wallets (their security is crap) don't invest in ponzis like cloud mining and never share your private keys. Also hardware wallets are good but you can also use paper wallets, which of course are basically free and have great security if you make them on an air - gapped system.
That is terrible advice in regard to web wallets. Web wallets are extremely useful as hot wallets because you can access them very quickly and from anywhere. The real, proper advice would be to use web wallets exclusively as hot wallets and then use a more secure wallet type, such as a hardware wallet, paper wallet, or brain wallet, as your cold wallet where you store the majority of your funds. I personally recommend using Blockchain.info as your hot web wallet, since it combines both convenience and security as it is client-based and your raw private keys and random seed never touch their server except for when storing them encrypted. All encryption and decryption happens client-side, so they cannot steal your bitcoins.
