Apparently, there's a minting process that was added to the Runes protocol, so you have to first commit to the symbol using a hash and then reveal some number of blocks later. I was going off of the initial blog post, but a few people have pointed me to the update of the protocol because they saw this same problem. Thus, the one dollar auction dynamic does not happen, though there's plenty of altcoins being launched. There's already over 1000 new altcoins either minted or in the process of being minted on it.
