Survivorship bias here. How many dozens of exchanges or defi protocols hastily shipped and got users absolutely rekt.

What large successful companies in the last 20 years have been slow and deliberate vs. ship and iterate?

That’s a different issue though. 

Coinbase is a ship and iterate and is more valuable than all the other products combined.

i don't know but the context here is crypto and as a user you can feel the consequences of this mantra. so much in this space feels rushed and held together with duct tape, and so so much money has vanished in to thin air due to imprudence and haste.
