500:1??? Seems Mtgox are buying all the coins by themselves, is there a japanese bank behind them? Say, this bank would like to support the bitcoin price as much as possible in a ten-years period with some of their spare USD reserve and acquire at least 20% of total coin supply
I dont know if its a bank (or whatever) but sometimes I do wonder about where those Gox BID orders come from. I don't want to derail my own post but (1) I'm often worried about the BID side on Gox because a ton of those orders are usually for 0.1 BTC. Those are small, insignificant orders but they can effectively pump up a price. When a large seller like me comes along, if I act improperly I can collapse the price by a few dollars (2) also, I always have my questions on the utility of BTC - what can you actually
do with it. I just don't see why so many people would demand it. Again, my ratio of sellers/buyers is like 10:1 - is Gox THAT much better???
On Point 1 above, ASIC scares me because you have to exercise good judgement when trading large amounts of BTC. I shudder at the thought of an ASIC newbie posting their orders on Gox
Obviously, I'm not trying to imply any malfeasance on the part of Gox or anyone else (Gox has a ton of positives going for it too) but I will admit that on some days I will cancel a meeting with a BTC seller if I see these types of anomalies on the Gox books and re-schedule for another day.
I think exchange is the most important place to decide a currency's value. Even for a large economy like Japan, their central bank still intervene with large amount of buy/sell to scare the speculators out and keep the exchange rate, unless some fundamentals changed, the exchange price will be relatively stable
A currency's value is mostly decided by a consensus (What can you actually DO with a currency? Exchange for other things), and that consensus typically comes from exchange. Since MTGOX is a very early supporter of bitcoin, I think they have the motivation to support the exchange price and promote public image of bitcoin, similar to FED printing dollars to artificially support the housing price (If amount of houses are more than amount of inhabitant, essentially the extra houses worth nothing: You can't even rent them)
Support the exchange price for bitcoin is relatively easy, since the supply is limited, in worst case you end up buying all the coins, and when demand rises again, even a little bit, there will be shortage of coin supply, the price will skyrocket. So the downside risk is small and upside potential is enormous, just throw in a couple of billion dollars and the exchange price will be supported. (Currently Bitcoin market capital is really small compared to real world economy, I've seen a single telecom equipment order from a japanese operator larger than 30 billion dollars)
If bitcoin's price rised another 100/1000 times, maybe it becomes difficult to support the bitcoin price, but by that time there will be other larger players, I heard many traders from wall street investment banks are already trading at MTGOX. If each of them are willing to put 1 billion dollars at stake, the downside risk is limited
Your ratio of 10:1 could be a indicator of recent sentiment after price shock in April, how is that ratio before April?
