I agree, the BTC price is kind of related to electricity cost. And that is a baseline, you normally get higher rate. There are 3600 coins generated per day and MtGox daily volume is at least 10x this amount, even all the mined coins are sold daily, it won't affect the exchange a lot. In a couple of months, when ASIC mining devices hit market at mass scale, difficulty will rise by at least 5x
I noticed that you still evaluate profit in dollars term, because you think dollar is a standard unit of value, this is a mindset difference. If you dig a little into today's money issuering mechanism and compare USD with bitcoin, maybe you will get less certain which one is the real bubble: At least you have to buy equipment and consume electricity to mine bitcoin, but FED just write a number of 0s in their account to create USD
A tricky question is: If someone just write some numbers in their account (say 10K USD) and transfer it to you in exchange for one bitcoin, will you give them your hard earned numbers in blockchain in exchange for these numbers created out of thin air?
When bitcoin price crashed, at least 400K coins were bought at 70-120 range, who do you think were buying those coins? Those people who writing those numbers
I don't necessarily evaluate my profits in $ terms. It's just that prices for electricity, food, GPUs to mine BTC and rest of it are at this point in time sticky with respect to $ or €. If and when inflation hits we will all quickly switch to another measure of value or we will index prices. Trust me on this one as I already have lived through hyper-inflation at one point in my life.
Whether this new measure of value will be BTC or gold or something else remains to be seen. But unless commodities are priced in BTC it is very difficult to imagine BTC will have a significant role to play.
To put is simply as I have in another thread. Would you rather have a 10'000 BTC or a $500k house for the next 10 years? And at this point in time 10k BTC is worth more than $500k, but if you needed to hold on to it for the next 10 years it is very difficult to be confident all those BTCs will be worth something in 10 years time. And everyone that would choose BTC over a house at this point in time must admit to himself that they are in fact speculating on the future value of bitcoin.
Why? Well let me list the rationale:
- first and obvious is the evidential reason: if people were bullish about 10 year value of BTC it's price would go up, and perceived future price of BTC would be influencing it's current price. Recent market volatility proves to the contrary: at the slightest nudge BTC holders are prepared to sell BTC asap. This is a market of speculators not long time holders. And for the record I still own about 5 BTC and did not sell a single satoshi in April. In fact I'm buying.
- then there is a problem of some early adopters who accumulated large holdings of BTC. Anecdotal stories tell of accounts with 100k+ BTC. These players can potentially wipe out the whole buy orderbook at mtgox. Since they cannot & should not be controlled, they are dangerous to the BTC. In fact my gut reaction on April 10th was that one of the whales have had enough, decided to get some hard cash and unloaded.
- let's be fair about numbers from thin air: where do you think most of my BTCs came from? They came from thin air as one of my computers got lucky and decided to think of a number that meant something. The analogy is perfect. All those BTCs can be traced back to a random number that somebody liked that I got paid for in BTC. Why is that fundamentally different from €? After all in both we can transact electronically. And at this particular point in time most people prefer to get paid in € or $ and not BTC. You can easily verify this by visiting your local shopping mall and check in what currency prices are expressed. Some folks from Cyprus may disagree which brings me to another point.
- the only fundamental difference is that with BTC new currency issue is limited however with traditional currencies this power resides with a central bank who has the power to issue new currency at will. Naturally every central bank justifies this power as means necessary to achieve price stability. To some extent they are successful. The only problem they have is working together with governments bent on spending more than they earn, and believe me I have seen this personally in the country where I live. For that reason we can all agree that fiat currencies created by central banks will fail, but... that does not imply that BTC will be successful. In fact commodity price instability expressed in BTC makes it vulnerable to speculation and failure.
- another comment about numbers from thin air: recently (about a month ago) I witnessed a very interesting development: namely I was minding my own business mining casually at slush's pool. when all of a sudden there was a fork in the blockchain cause by software glitch, which slush had lost and we miners got a big fat 0 pay for 6 blocks or so. which was nothing in particular. but then after a few weeks I noticed a post in the pool's thread that "bitcoin committee" or someone had decided, that we should have gotten compensated for those 6 blocks and that have gotten paid somehow. Now those BTC had to have gotten from somewhere. And as much as I think Marek aka slush is a nice guy I doubt these came from his pocket. Now if "committee" somehow allowed for these BTCs to be created don't they have the same powers as a central bank??? Who controls BTC protocol? Public vote? Committee? Who are these people?
So we can all agree that holding $ or € for a long time is not a smart thing as these currencies are likely to loose in value=purchasing power.
We can also agree that volatility of BTC makes it unsuitable as "store of value" as of now. It still is a speculative market without many rules set in stone.
And yeah I'd take those $10k today thank you very much
p.s. naaah, I would probably go out to buy a couple of graphic cards, and would just raise the difficulty for everyone, so... not such a good idea.
