Like the thread title says.
I bet alot of people are still strugling with if they should invest in bitcoins or not.
I am not really talking about $10 or $100 but really invest $1000 or more in this whole thing. (this may be in the form of a mining rig or just pure USD/EURO money)

What is your main reason you do not invest in BTC with huge amounts of money?

(The fact that you cannot afford it not included ofcourse)

My top 3 is:

#1 I still do not understand the system good enough. I cannot answer each question about Bitcoin with a legit answer. Wich makes me doubt about it.
#2 I do not know if everything that is being said about bitcoin is true. And I cannot research myself since all information out here that i can base logic on can always be false. You never know.
#3 Like the stock market, this whole thing can collapse in a matter of days cause of some major development within the system.
