Why?
I can understand if you're saving to buy a house outright for cash, or to invest in a startup that needs a chunk of capex at the beginning, or something, but just sitting on a pile of depreciating cash assets is silly in an economic market where retail inflation is running at ~10%. If you're literally just holding cash because you can't think of anything fun to spend it on then that's quite sad.
No, you don't want your entire "life savings" in cash stored in pillow-cases under the bed, but you do want enough cash where the value of "enough" varies depending your circumstances.
I don't think OP means 300k cash, but (cash + mix of investments) = 300k.
For all we know it could be 10k cash and the rest investments.
Could be, but regardless, it's very unlikely that his investments are beating inflation at the moment so the point still stands. By holding on to the money its value is shrinking.
You’re basically saying everyone should spend everything in a downtown, and if they don’t they are boring?
Probably $80K to $100K for that, plus extra for snacks. :)
