I think it will help all the beginners to improve there security in crytocurrencies..............

The safest way to store your airdrops are hardware & cold storage wallets. These wallets store your coins offline, and therefore protect them from being hacked. There are a number of hardware wallets available. We would advise to use the Ledger Wallet Nano S or Trezor.

Not all cryptocurrency can be stored in hardware wallets. We advise you to store your crypto in wallets where you control your private keys. You don't want your free crypto to be stolen!

To avoid scams we have a few general rules:

Never give your private keys!
Use 2 Factor Authenticator on your wallets
Be careful downloading wallets of smaller projects
Never click on links redirecting to wallets
Dont use your main email address to apply for airdrops
Dont re-use your passwords when you register on a website
Dont send small amounts of crypto to receive your airdrop

In addition to the methods you mentioned, you can also spread your investments in multiple exchanges to remain safe. In case one exchange is hacked, your investment in other ones will be safe.
