To secure your funds, I would suggest everyone buy a Ledger hardware wallet! The price is very cheap. If you can't bear the present price of Ledger/Trezor hardware then wait for the Black Friday when the price will be 50% down than now and buy it!
It is always best to use Ledger/Trezor rather than any kind of wallet so far. Well there are other hardware wallets or even paper wallets but Ledger and Trezor have always been the two most trusted in terms of security and safety of coins. There is no need to risk on hot wallets when you can afford to buy even the cheapest Ledger. In terms of saving seed and PIN, it is better to go back to the old note and pen technique rather than on soft copies which could still be accessed online.
