While news coverage is certainly the most ephemeral of fundamentals, several people in this thread are making the familiar basic error of confusing absolute growth with relative growth. It's like scoffing at the miniscule growth of a penny stock, from $0.01 to $0.03. "What're you so excited about? The price hasn't changed hardly at all. It only grew two cents!"
Same psychological error, different angle. Now I see why rpietila wants to price things in mBTC; it's a natural compensator for this human tendency to confuse the absolute with the relative (a very expensive error for investors).
tl;dr Bitcoin is unpalatable to HNWIs (who account for the new Coinlab & Tradehill customers) because it is has the unique combination of being unregulated and very high risk, a bad combination for most portfolios. Lacks of these investors imperils the future.
Pricing in mBTC certainly wouldn't change my mind. I would be hesitant to buy Litecoins after such an enormous run-up regardless of the low price.
The risk is too great at current levels with lack of solid fundamentals. For BTC to be palatable to the wide range of investors that would be needed to make Bitcoin successful, with success defined as $10K to $300K per coin depending on the dream world to which one subscribes, it will need to be regulated by the CFTC (or something). Without the ability and ease to trade in a broad range of bonafide brokerage accounts (through legit custodians), and without some type of regulation for investors, the general public (and the 99.9% majority of HNWIs) will never be confident enough to purchase Bitcoin as as investment at current levels because wealth managers will scoff at the extraordinarily high systematic risk. And forget about institutional money directly investing in Bitcoin until it's regulated.
Because of these very large hurdles to success, IMO the odds of Bitcoin success are much lower than what most of you think. Whether one uses NPV, which doesn't really make sense because there are no cash flows, or EMV, which is probably better because BTC is more similar to wildcatting for oil, at $122 the math doesn't work for me because I see success as a truly infinitesimal probability (with a negative EMV). IMO there are several possible outcomes over the next couple of years, not simply success at $10K+ or failure at $0. We could meander along for awhile with constant hope of the next big development. But in the long-term, there are only two options..$0 or $??.
This makes it difficult for retail investors and the vast majority of HNWIs. I don't know many hedge funds that purchase lottery tickets as a business model. Lottery tickets are $5 (I believe??) and have 100m to 1 odds with a $100m+ payout. Bitcoins are $122 and have 1000+ to 1 odds (IMO) with a $10K potential payout. Even at a potential $300K per coin, just because there is a large potential payout doesn't make it a good investment because there is still the overwhelming likelihood of losing the investment. If you had $1M in liquid assets, would you invest $100K in lottery tickets that had a combined potential payout of $10M @ 1000 to 1 odds? I wouldn't, regardless of whichever method one uses to assign value to the investment. I wouldn't even invest $10K....or $1K.
What scares me about Bitcoin is that its price is fully dependent on finding the next round of investors, which at some point will be fully dependent on being institutionally recognized and regulated. The current price is the outcome of hoarding and speculation and has little to do with transactional volume. BitPay sells BTC immediately on the open market to hedge risk, so if current holders started making large purchases through BitPay it would probably make the market trend lower. There is no reason for someone to go out and purchase BTC to pay for something through Bitpay if they don't already hold the coins. Why go USD to BTC to USD?? BTCs success will be due to, in addition to making it palatable as an investment, its niche use in transnational transactions.
BTCs strength is crossing borders. It's weakness is that unless one already has a reason to hold Bitcoins (reason is currently mainly investment related), it is unnecessarily cumbersome and pointless to buy BTC that will simply be converted back into USD by the merchant (through BitPay) when making everyday transactions. So, in that sense, everyday use of Bitcoin within the borders of the US is still very dependent on it being accepted as an investment vehicle primarily because investors holding coins will be the ones using BTC to make transactions. This is one reason why BitPay adoption doesn't really excite me.
Stocks, bonds, gold, real estate, timber, private equity, etc etc, are all risky. But the investments are regulated, vetted, or have low volatility and fairly determinable risks. And unless one utilizes debt and leverage, illiquid assets usually have recoverable values. All-or-nothing types of investments are usually considered extremely high-risk (wildcatting, although wildcatting has much better odds) and is not something that the general public could/would ever get behind. The small gambler willing to put $500 or $1000 into lottery tickets may keep it pumped (is the best thing to keep it pumped), but will not sustain the full embodiment of Bitcoin a la $10K+ coins.
