Buying coins directly is nothing but flat out gambling on price. Bitcoin is nothing but a lottery. Anyone who wants to wager on Bitcoin as it exists now is nothing but a gambler, and they could just as easily do so on some real world outcome in Vegas.
And you're confused as to why?
LOL.
If you want to make Bitcoin real, spend more time on making it a stable currency and less time wondering why people/businesses won't use it with 40% daily value swings.
Real?! Yeah, you're talking out your ass. The list of companies accepting Bitcoins as payment is vast and growing, including big name retailers (read Virgin Airways, Virgin Mobile, T Mobile, Subway, Overstock, Microsoft, Namecheap, Newegg, Steam, Starbucks, Dell, Whole Foods, Dish, Tesla, Fortune Magazine, Lamborghini and McLaren dealerships, Re/Max London, etc. etc.)
Upwards of 300,000 stores and restaurants in Japan will be accepting Bitcoins by the end of the year.
Yeah, there have been some big swings. Yes, it's volatile. So what? For every swing there has been a price increase. It's not going anywhere.
