That means bitcoin is no more accessible to you and me than the dollar is, and people know this now. There's not really any reason for any sort of volatility based on any vendor taking up the currency because of it.
In fact, the looming financial regulations that are going to be slapped on bitcoin are probably going to do far more than any Amazon or even Walmart could for the currency at this point.
Mining bitcoin isn't supposed to be the only reason people like it or use it.
It has several useful properties, disregarding mining.
-the only "inflation" is the known production of bitcoin through mining, which should occur at a predictible rate. This removes the possibility of the usual kinds of hyperinflation, caused by governments printing absurd amounts of paper money
-despite all the stolen wallets and such, it does have several advantages in the safety and convenience arena. You can easily buy online with bitcoin, and it doesn't give the vendor or anyone else your credit card numbers. You just need a name and shipping address and you pay, it's incredibly easy and a nice refreshing change from the usual, and you don't have to trust the vendor with your financial information
-very easy way to sent small or large payments for any reason. sending money to kid at college, sending a small tip to someone, paying back your buddy who got lunch for you, etc. paypal can do these things, but at a much higher fee generally.
I think it's actually really good that bitcoin has been so stable lately. Historically, all the big run-ups in value occurred after a period of stability. Past actions don't guarantee future results, and other usual disclaimers apply, but I remain hopeful.
Value of bitcoin will continue to go up as usage spreads, it's simple math- the more people using bitcoin means supply is relatively lower and demand is higher which pushes value up.
Quote me on this 5 years from now- there will be a day in the future when people look back and *wish* they bought those cheap bitcoins for only $1000 each.
