Everyone and their hairdresser is now aware of bitcoin...
I ask at least one cab driver every week whether they have ever heard of bitcoin, and have done for the past year. Keep in mind that these people are overwhelmingly recent immigrants who make regular remittances to family overseas, a first-order use case for bitcoin, which would save them as much as 10% on transfers of thousands of dollars each year.
Exactly one has ever heard of bitcoin.
Regular Joe wont go to bitcoin because of fear to be hacked. Unless one will create way to keep bitcoins safe from bad guys and easy system how to pay for goods and services, mainstreamers will stay away from BTC. Myself I'm tech guy and even I cannot sleep at night because of fear being hacked. Imagine someone not that techy, family with kids who use that computer to play games, install screensavers with all the viruses and keylogers. I dont see adoption without 100% security solution.
Fear of being hacked. An easy to use and nearly unhackable wallet. An easy to use and nearly unhackable means of obtaining bitcoin. These are all still hurdles for the regular joe. I had a 50 year old programmer co-worker on coinbase, trying to set up an account so he could start buying BTC. The process was long enough and complicated enough that he got bored and put his money he was going to buy BTC with into a semi-legal online poker site. Yes, he wasn't the guy that was going to send us to tha moon, but if someone who is technical can't figure out one of the currently easiest means of getting BTC, a non-technical person still has no shot. Those things need to come out from the companies doing that work, and then we will see greater adoption rates.
