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?)
To hodl cryptocurrencies, one must know and decide on how they get the funds they want to hodl, either to hodl only money received for payments or to fund the wallets and hodl for a duration that is seen fit. It is however to note that to get the best return from HODLing as a strategy of investment, one should try to hodl for a longer duration that may be up to a decade or more.
About the kind of wallets to use or how many one should use, it actually depends on ones financial and emotional risk tolerance capabilities and management skill, else, how would one aim to manage three wallets simultaneously without losing seed phrases or falling prey to hackers or scammers.
Therefore, it is good to use cold wallets or air gapped wallets for longer term plans and hot wallet for easy access and top case use.
