Re: What fears did you have when you first started dealing with Cryptocurrencies?
When you first went head first into the unknown,what were your thoughts? What were you afraid the most? 
I fear of being hacked or unknowingly victimized by a phising sites that will attack me when my investments become more successful. I had a lot of fear the first time I tried cryptocurrencies since I am not techy and well known around the net and about trading. Its a good thing I spend a lot of time here in bitcointalk since I usually got heads up about threats and information that can help my trading ventures.
As far as I read from comments most of us has similar fears. The main fear I have is that next morning I will wake up and see that market has crashed. Second biggest fear is that as you say hackers will hack my wallet and I will lose everything I have.
