Bitcoin is a Currency or Bitcoin is a Commodity?
in answer to that question, bitcoin is becoming either a "stock" or a "commodity" and may soon be an accepted full-bore currency
it is treated more like a commodity, but the price is more like that of a stock
a commodity is something like "corn" and its value is set almost strictly by the current market, it is hard to affect the price of corn without buying or selling corn or altering the overall supply. if farmer joe is the second largest supplier of corn and the price of corn is $5 per unit and farmer joe buys a new fleet of tractors, the price of corn is still $5 per unit, if he sells his farm, the price of corn is still $5 per unit
a stock is literally a piece of another persons company, the term comes from years back when a farmer or tradesman needed help to make their business work. say the farmer joe could not afford the seed to plant his crops this year, so you came along and bought the seed for him, in exchange you now own 15% of his next crop yield or 15% of the "stock" that would come from his harvest, or a store that needed help getting started could sell you 15% of their "stock" in exchange for the start up cost for the business. now, the value of a stock is mostly set by the overall market cap of the business and the percentage of stock that you own. market cap or market capital is the basic value of a business. from the commodity example, farmer joe buying new tractors for next year might have an even effect on his market capital, he spent $500,000 and received $500,000 worth of equipment owned, in part, by the stock holders. BUT, stock prices are also affected by what a person is willing to pay for that stock, JUST LIKE BITCOIN
if i go on the stock exchange and present 500 shares of stock for sale and the market value is $500 for them, i can literally put in a type of order that says i will sell them at $50 instead of the $500, i can quickly unload stock that way, that means that a buyer will be able to buy those stocks at well below that market value, enough trades like that and the overall market value will begin to drop, or i can put out the sale at over the market value and hope that someone buys them, if this happens enough the stock value will rise. so, when i see that the very successful farmer joe is buying new tractors, i just might pay more for the stock because i see a banner year coming, the price starts to rise based on nothing more than my opinion of the coming year, making the stock market fickle in some ways, subject to rumors, opinion, and conjecture, JUST LIKE BITCOIN
the overall price of bitcoin is set by what the market will bear. if i go to an exchange and buy bitcoin from someone at just more than it is currently valued it can cause the price to rise, the more btc i buy, the more power i have over the price. so, even though it is around $475 at the time of this posting, if i can go to an exchange, put out a sale ticket at $600 and get someone to buy it up, or several people, i can bring the value up. at the same time, if i put 1 btc on the exchange at $350 i can cause a value drop, these are, of course, directly proportional to my buying/selling power(how many bitcoins i have) and the period of time the transactions take place. there are those that have gotten with another person and tried to spike the price by putting in a sale for twice the current value and having the other person buy it up, they do this with half of their total bitcoin wallet and hope that the price shoots up for a short period and they can then sell the remaining half at an inflated price. the exchanges cannot be messed with that easy, it takes a lot of sales, over a period of time to alter the price, or a short period of time and VERY big volume
just remember, it all started with a small group of people trading BTC back and forth and that was pretty meaningless until the first person was willing to trade something of real value for some BTC and the first person that paid true FIAT for bitcoin, that was when a couple of thousand lines of "value-less" computer code became something that will likely change the economy of the world. Everything is worth exactly what another person will pay for it, exchanges can list a bitcoin at $100 or $1000, it means nothing until a person pays that amount for it
