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?)
I believe everyone should have at least two wallets, probably one cold storage wallet, this wallet will hold the majority of your funds, it can either be in an airgapped wallet or in a hardware wallet, this wallet will never be connected to the internet, ever. You other wallet or wallets can be online wallets, and they will only hold a small amount of coins which you use for spending on the go, or for testing and other different kinds of stuffs.
