For me it was one big question: How can it be fucked with?
This took way to much of my time, mostly because of the blocksize war and the exchange hacks. I couldn't understand why people were not hodling their own keys, why would they borrow against the corn or why gamble with it at all.
Than I remember that everyone is a trader, greed is eternal and just because one is early doesn't mean they'll get to keep it. Temptation is a bitch.
My eureka moment was that this is the fairest thing ever.
