From a stand still, 7 devs toppled Opensea in 400 days. There are lots of very good lessons in here. I highly recommend everyone listen to this. Specifically they took a different approach to their air drop that prevented wash trading. It rewarded liquidity, which attracted REAL activity on the network and exponential adoption.
The founder started out as a high school dropout and graduated from Y Combinator. He thinks on a different level. I really enjoyed this one.
