The first one had a payout of 10 btc.
Actually to be precise it had a total payout of 15.1337 BTC. From the blogpost in question:
I am going to reward your efforts, in Bitcoin. Specifically: the best entrant will receive 10 BTC, the 2nd best will receive 3 BTC and the 3rd and 4th best 1 BTC each. Also the 7th best will receive .1337 BTC, to keep things interesting.
Anyway, for the sake of theory I've put in the work in to dig up the respective twitter announcements. The April contest:
0 retweets, 0 favorites, 1 reply. This contest:
146 retweets, 1 favorite, 0 replies. The difference might be explained by this one including a "please RT" call to action, maybe. I ain't doing the reddit digging tho.
btw
You are the most unconventional PR rep I've ever encountered. lol
Yes, it's one of those things Bitcoin is famous for. Sorta like Naples has the leaning tower and Pizza has the pepperoni and cheese. Or whatever.
