What events in crypto history will be remembered in it's myths and legends?

There are obvious examples like the genesis block and the news paper headline embedded inside, the 2 pizzas for 10,000 bitcoins, the Ethereum DAO hack and subsequent fork. Bitconnect... MtGOX...

What other events rise to this scale of historical memory? There are many small hacks and controversies that happen all the time but what are some that alter the trajectory of the entire ecosystem.

Also, try to think of positive things, not just hacks or controversies.

I'm sure some of the facts about these events will be emphasised and others deemphasised and that is part of what helps with the transmission and memory of these kind of legends.

I am excited to read your ideas so thank you in advance.
