It doesn't seem like you've factored in the kinds of changes - "mass-adoption" (or at least evolving mass-awareness thanks to increased media coverage), developing services, etc. - that have led to some calling this the "tipping point" for Bitcoin. Of course it is impossible to give precise mathematical indicators in this respect but qualitatively speaking things are not the same now as they were historically. That said, the December 18 low of $450 fits well in comparison with history.
We are nowhere close to mass adoption, not by a long shot. I just spent dinner with my extended family where there were five middle aged wealthy men attending (not overly wealthy, just have nice jobs, equity in their homes, investments, et cetera). Not a single one of them knew anything more than Bitcoin by name. NONE of them were interested at all in investing in Bitcoin, too risky, too strange, to difficult to even understand for them.
I spent 15 minutes discussing Bitcoin with the most open minded of the bunch. He wanted to know what he would do to even buy a single coin. Holy crap, what method was I going to suggest to this guy who can barely get Skype to work correctly. I chose a paper wallet and Local Bitcoins. He thought it was reasonable, however, i could tell by the look in his eyes there was no way in Hell he was going to invest a single dollar any time soon.
The masses ARE NOT early adopters, they will not do research, take a chance, learn about digital wallets, trust some web site exchange or anything of the sort. If it isn't offered by their broker, or banker, or something they can buy at the local Gold dealer, then they are not interested. BITCOIN right now seems a world away from this mass adoption. A WORLD AWAY.
We are still in speculative, niche phase that has a long way to go to play out. It is the biggest reason Bitcoin can fail because if another Crypto steps in and solves these access problems look out. Guys like those in my family DO NOT going to care about the virtues of Bitcoin's distributed, non-regulated, anti-govt protocol. They will invest in the first thing that is 1) accessible 2) available to them through standard channels 3) endorsed by things they trust: banks, govts, large companies.
That said the price may go to $2000 in the next month , or $200....
agree
need someone to make bitcoin idiot proof and attract the masses
