Hello,
If you want to hodl, what's the best strategy for doing so? A single wallet or several? What are the advantages and disadvantages of both options? Maybe it's stressful to use a wallet with lots of satoshis? (whereas several with fewer satoshis is less stressful, isn't it?)
in the end everything boils down to your preference
Single wallet would be easier and would reduce the risk of having too many private keys to secure
While multiple makes it that all your coin ain't in one basket.
In the end, how your private key is protected and safeguard matters.
It depends on your preference, but to minimize risk, having more wallets is better, and they should be hardware wallets to ensure they won't be hacked.
Hardware wallets? Except the funds separated are worth it.
i.e worth more than the hardware wallet,
If not I don't see the need of having that much hardware wallet.
