Existence of VC money is irrelevant to 'bootstrapping'. Taking VC money is sort of the opposite of bootstrapping.
I'd rather have 20% APR, than give away 20% equity. Why? Because when the debt is paid to the credit card company they go away. The VCs will always want more and more, pushing your company faster than it should go.
30 with 3 kids and no savings? Yes please, give away some of my profits so VCs can derisk the startup.
20 and living with parents? Bootstrap away, if I fail I will be fine.
