I personally don't think it is. If you assume these statements are facts about bitcoin I think the price is just bound to go up as one poster very astutely pointed out in the thread
https://bitcointalksearch.org/topic/bitcoin-vs-world-money-supply-what-happens-when-max-cap-at-max-supply-1951431 that I think it (the market cap. getting to 80.9 Billion USD) will take less because there is a "learning curve" associated with using Bitcoin.
I've been eyeballing and analyzing the year, monthly, etc.. interest rate. I understand there was a steep curve at first, but Bitcoin is now transitioning in the upward direction.
In the biological sciences, there is something called a doubling rate. This relates mostly to bacteria and other microorganisms. Bitcoin is like a biological pathogen (coinmap.org) in that it has an epidemological aspect to it (it's growing like a biological organism). The doubling rate is getting faster (4 months now?).
The interest rates are going to be ridiculous (up and away). Social change is going to be ridiculous. I've read the power behind it is greed (I'll argue people want to see changes THIS--right here and now--lifetime). As such, the here-and-now desire for social change is propelling Bitcoin. Given that there is so much technological output (ability to track how this thing is moving), it's growing at a very popular rate now.
Society is learning to use Bitcoin. Simple as that.
From my background in studying psychology and learning, it appears that the curve is taking the form of a learning curve, whereby exponential learning is occurring: Market psychology--people are taking to Bitcoin. Also, the methodology that Bitcoin uses is pretty legit and works with the law of entropy: The thing is that the whole system resides on Earth making it really easy to manage.
Furthermore, I've read of Bitcoin fitting onto an S-curve (source:
http://woobull.com/woos-law-of-bitcoin-user-growth-bitcoins-adoption-curve/).
Bitcoin isn't moving like a stock market ticker. It's kind of like a stock but only a very, very, very small amount.
I however, in so many words tried to point out that the sample size just isn't big enough yet to know for certain whether or not we are seeing this exponential growth but while I totally think that "social change is going to be ridiculous" is a little bit of an overstatement. Exponential growth is a function in math and seen all throughout nature and the physical world.
While I agree the price of btc is bound to do nothing but steadily go up over time I do think there are possibly some real parallels between what we're seeing and
https://en.wikipedia.org/wiki/Exponential_learning . When I first saw the market during that huge jump it did seem to be exponential and it happened in a fairly quick type of way and then stabilized again except at the above price. Does anyone know the biggest decline as well as increase in price per BTC over it's 8ish so history? That was also my first reaction when I saw a visual representation of the value of btc over this few month period was that of an exponential curve.
While I agree with the poster quoted here that we are seeing some ASPECTS of exponential learning affecting the market price of btc it's hard to tell when this will stop as people MIGHT lose interest or go with other forms of currency. However, I am seeing some serious growth potential here with btc's value if you assume that it's positively correlated with people's ability to use the currency. A bubble implies some error in speculation (which drives market forces) from people at large in the value of a commodity such as with derivatives and housing lending in the late 2000s but from my understanding bitcoin's entire function of exist and creation (of decentralized e-currency) is the thing that's bound to drive it up. It's meant to work more effectively with more users and people are only bound to learn more of it over time. I know that I personally wished I could have seen how valuable a resource such as btc was and I was even shown by someone pretty savvy at IT when it first came out. (him using his wallet only on a USB drive on ubuntu).
I also do see a correlation here between moore's law (another exponential growth curve) and bitcoin as tech becomes more available and more cheaply distributed people's ability to learn the system becomes even greater thus increasing the value of bitcoin. This is why I don't see it as a BUBBLE per say I just dont know when it will level off (could have already).
Right now as a newbie "investor" and purchaser of bitcoins I am personally worried about the volatility of the market and how secure transactions truly can be. The world's primary exchange currencies are time-tested and have safe-guards automatically in place for the protection of the ignorance of the general public such as a very robust legal framework for the handling of large sums of money such as insurance and protection against scammers, theft and hacking. Not to mention regulations against crimes such as fraud, corruption, insider-trading, etc. With bitcoins I don't see any built-in safeguards outside of the transaction history which is just logged onto a single IP, and who is stopping anyone from hacking into your IP or using a proxy while making purchases? Not to mention who's stopping private companies such as exchanges and gambling sites from defrauding investors by blaming some outside cause or simply withdrawing all the funds from their clients' accounts and skipping town? This is not even mentioning obvious threats by phishing sites and hackers to simply empty your entire wallet.
In the end I believe if you believe bitcoin will become more and more an accepted medium of exchange, especially for larger transactions, such as buying larger EQUITY such as a nice home, business or other valuable property than the price will most definitely go up. The only question is how soon will this happen. I also made a thread wondering also if government regulation and taxation of bitcoins will drive up or down the price?
