I think a fabric/platform coin will more likely be the second most valuable coin at some point. Though I am not sure it will be Ether. There are some serious problems with scaling over there that aren't entirely clear how they will solve them. Either way though, I'd say yes when things are more accurately valued a fabric/platform coin will be the second most valuable coin, possibly the most valuable coin. Though I think bitcoin will always be up there as a store of value.
