how could this happen? there should be a central authority to bitcoins regulating daily loss of maximum 5% per day!
Is not sure if joking.
The exclamation mark suggests to me that he's trying to be funny, but I could be wrong...
I wonder who he would want to be this central authority? Assuming that he isn't making a joke.
I'll do it. Send me 5% of your bitcoins every day, and don't spend anywhere else. As long as you follow my instructions, I promise you won't lose more than 5% of your bitcoins per day.
