So it is a good practice to have a variety of wallets then?
For example,
Laminated paper wallets kept in a secure place - for long term storage (6 months and above)
Hardware wallet like Nano Ledger - for day trading (Qs: How often do you deposit/withdraw funds from exchanges into this wallet?)
Mobile wallet - For small misc transactions
or if you want to use it to make purchases, then you won't really do it with 10, you do it with smaller so put that smaller amount (like 0.1BTC) in a place where you can access it easily. it can be your desktop wallet, your phone or if you really needed it a web wallet but that should be the last resort.
When it comes to "splitting" assets into smaller amounts, can you explain why you should do so, and
how/where you will split them? If it is for security, how does splitting them help? If it is for convenience, I feel it is counter-productive. Or is it related to cost of transaction in some way?
