if you are still in the stage of being an investor you can use myetherwallet wallet to save your coins. but if you already get the coins you have you can save in the wallet offline to make your coins safe.
That is right. Myetherwallet is a good wallet to start. You can use without any hardware wallet till your capital grows to some level. After that you can use mew together with ledger nano x to make it more secure.
I'm thinking about buying Ledger Nano. There are a lot of phishing sites and bugs that can replace the right site with a fake one in your browser. Your private keys on another safe medium are the best solution now.
You do not need any ledgers if you do not open your wallet through your private keys. Use authorization with MetaMask on MEW site and keep your private keys in a cold store
