Having seen a lot of crypto founders as an investor, some common pitfalls I'm trying to be careful of

- raised too much, lost sense of urgency
- grew team too large, lost focus
- ego caught up in speaking events and vanity metrics
- nerd sniped into building fun things
- waiting too long to launch / release feature

'nerd sniped into building fun things'

I once made this exact mistake in one of my startups. I was so obsessed with the technology that I built things into my code that didn't add any real value to the customer.
It took me away from the important things for far too long.
