Did you say 5-10% annual ? Pass
What kind of returns are you expecting?
You have to understand bitcoiner believe the value can increase much much more, from $10 to $1000 in 2013, many expect it to go to $5000 or $10,000 in 2014. No bitcoiner is going to be interested in 5% return on their coins.
Sorry, not trying to offend you, just explaining bitcoiners mindset
