Hardware wallets is a good pick, but a expensive one. If you're worried about security, learn something about paper wallets and you'll be fine. Do some for each coin that is possible and chill. One more hint is don't store everything at same vault, split your coins into some wallets, so if some one crack it, you'll lose only some coins and not all of it.
Is it too tiring to just put your coins on a different wallet, it will somehow create a confusion to the user although it looks like a good advise but buying a lot of hardware wallet will cost you more i guess rather putting it on a single wallet. But for me i would rather prefer the paper wallet instead of hardware a wallet, i just think it is comfortable and safe.
