Thanks. These are really helpful. I am still thinking about my options here. May need a few days or even a few weeks to think about them and finally make a choice.
I am seriously thinking about going for a hardware wallet. But not finalized as of yet.
Hardware wallets would be much safer since you literally are saving these coins for the long term. And like you said it's your retirement funds, you have to do all it take to keep them safe from scammers or being lost. Get a good hardware wallet or create a cold stored device using electrum and sweep your private keys there to store your coins, so you have full control of them. With many reports I've heard about blockchain.com here on the forum, I won't want to think about using their wallet to store my coins. I prefer just electrum or a hardware wallet..
