I very rarely carry cash. Most of the time ill have less then $5 on me at any given time(just enough to buy a coffee type of thing). Ill put everything else on the cc as it makes it easier to track what I spend my money on.
When it comes to bitcoin I keep about 0.5 in my hotwallet at any given time. Where I live there isnt really much I can buy with bitcoin so I use it more to give out a little when I find people that are interested in bitcoin(tend to give out about $5 when they show some interest).
