if the quantity is large we recommend you to try to get a hardware wallet, for example like Electrum they say so far very safe. maybe there are some other trusted secure hardware wallets you can try.
Electrum is not a hard wallet. Electrum is a software wallet
Aside from these recommended desktop wallets.

- Samourai
No, Samourai is not for desktop wallets, Samourai is just for phone wallets/for Android only,
except Whirlpool.
In the end, the winner is Electrum wallet. I trust not to regret this but will not buy in large scale at first.
