[I see @happybeing said part of this while I was writing and otherwise distracted, but here it is anyway.]
I think it’s not that anybody pegs altcoin values to bitcoin, it’s that bitcoin is the key gateway to trading in them, so that’s where the price discovery is most broad. One can always figure the momentary conversion all the way to any fiat currency or altcoin you want, it’s just not convenient or stable because there aren’t enough direct official/public interfaces to make broadly agreed-upon price discovery directly.
The hurdles are high enough for bitcoin/fiat conversions; it isn’t too worth it to jump them for all the various altcoins. But Shapeshift is leveling that field by making trading pairs of most any altcoin/bitcoin or altcoin/altcoin easy and fast. Altcoin values are always shifting in relation to each other, as well as to bitcoin, and thus fiat.
Maidsafecoin fits the same parameters as other altcoins, but safecoin will rather certainly break the mold. The granularity of distribution is going to be very different from any altcoin, and especially different from bitcoin. Because anyone who wants to run a vault (easy and cheap) to have access to the network (which is the real prize, not safecoin), I think that very quickly we’ll see a lot of commerce being done directly in safecoin, bypassing the chokepoint of currency exchanges.
Almost all the action in the altcoin/bitcoin trading sphere is a speculation game, loosely related to what people think might have value in the future, as compared to fiat, which is all they know. That’s also true of Maidsafecoin currently. All that has almost nothing to do with actual use, either as currencies or other functions. Just speculation. Can’t really be otherwise.
Bitcoin itself is slowly starting to climb out of that gravity well as its utility is recognized and spread through improved usability and understanding (PR), as well as adoption by more major institutions. It’s relationship to fiat currencies is really the only one that is important right now, because it is starting to gain value as real money. (Don’t know how close to bottom it might be, but eventually it will end up going way up, I think.)
Again, safecoin is quite certain to take a really different arc due to what I said above. Almost anyone will be able to get access to it, either by running a vault and starting to get some, or acquiring it from friends or acquaintances who get it. It has a real and tangible tie to real value because of its utility on the network for network resources, so it doesn’t have to get all of its value from somewhere else. Even bitcoin is just starting to be recognized for value other than transactions.
So if the SAFE network works, safecoin will have a value quite aside from its superior currency properties.
Sorry, I can’t help but roll once I’m faced downhill.
