This is such a sham. Here, I'll offer $2000 to break my plaintext crypto. Every morning, in the shower, I'll say a secret word. Email me the secret word and I'll send you $2000 in BTC.
I'll need to narrow it down further, but I'm pretty sure it's one of "Oh", "god", "groan", "I'm", "running", "late", "for", "work", "again". Hrm, does groan count as a word? How many guesses am I allowed?
The code is open. It's more or less the same if you tell us your address.
You say "cold". I use the same plaintext crypto =)
