@pkalra thank you for mentioning my post bro...
It's always been a pleasure discussing things with you, Lets make the options you mentioned in the order (in my opinion)

1. Hardware Wallet (The best option because, it needs to be physically operated in order to make any transactions)
2. Paper Wallet (Always a cheapest, almost free and best option as your private keys are always stored offline)
3. eWallet (If no hardware wallet is available and paper wallet is too confusing for newbies eWallets that provide with private keys or seed phrase can also be considered)
4. Exchanges (Should be the last option in my opinion because all the major exchanges are centralized and you don't control your coins as you don't get the private keys)

Hope that'll help, please correct me if i missed something...
