Thank you all for the thorough replies! I’m sold on cold storage now. I just purchased the Ledger Nano S.
Good choice for you. Well, congratulations, now you do not have to worry if your wallet will be hacked because you have full control of your wallet. Do not forget to make a backup of the private keys, password and else, so you can recover the wallet if something bad happens. Take care of your wallet and do not tell others if you have crypto inside the wallet.
