One cannot argue that mtgox is quite naive in terms of "market making"... mtgox with 80$ share in THE market for bitcoins. The delays caused by huge lags and other technical issues have only exacerbate volatility. If bitcoin becomes too "hot" or volatile a currency for any serious entity to conduct meaningful commerce with it then that could spell its doom. Current backers argue that the anonymous and worldwide instantaneous nature of bitcoin transactions and an upper limit on the total bitcoins in existence command a high price for a bitcoin. After all, there can only be 21million possible to come into existence, there are 7 ? or 6 billion people on earth. On the other hand, detractors say that there is no intrinsic value for a bitcoin, such that if one were to amass as much bitcoins in existence it would not be worthwhile because its intrinsic value is 0$ if everyone in the world suddenly stops accepting it as a medium of value. That wide gulf in opinion along with a poor trading infrastructure either by design or accident is what is causing the current wild swings in current prices.
Now what if an altcoin upon its inception was backed by a prize. let's say 20million $ in gold for 20 million said altcoins and only 20 million with similarly a 21 million coin upper limit. Theoretically, it would have a book value of 1$ per coin (not taking into account discount/premium calculations that would affect its present value). So assuming its "mining" infrastructure would reach a point at par with bitcoins, speculation on what should the value of this gold backed altcoin would be tempered as it would affect..
1.speculators argument that its value should shoot to the moon because another viable altcoin with all the features of bitcoin has been created.
2.detractors argument that it is worthless, it is has a prize $20 million worth of gold for 20 million said altcoins.
Now my argument could definitely be too simple to create intrisic value for this altcoin, because...
#1... one unit of said altcoin is worthless, you must get 20 million out of 21 million to get the prize. How should one value 1 unit? What if everyone see that the condition of getting 20million coins for the prize is intractable then the value of one coin might as well be worthless.
#2... what if the database is corrupted or forked??? what will happen to the prize, that being said, the same thing can happen to bitcoins...
#3.. other nuances or details just hast come to my mind yet..
Another possible solution is to pre-create the altcoins and "sell" them at book value, but then who would "mine" for the next block?
