It is not about t he device used here mostly, but the kind of wallet we operate on and how we secure the same device from anything that has to lead to an online internet connectivity, the wallet we are going to use should be a non custodial wallet and we should for no reason consider for a custodial type, then the device should preferably stand out different form the one we use for normal internet connections.
Noncustodial wallet shoukd be used but it should also be open source and not close source. Online wallets should be used for the amount of money that you can afford to lose while cold wallet and properly setup multisig wallets should be used for high amount of money.
