There is nothing new here. FinCEN has issued guidance over two years ago that makes a clear distinction between a Centralized Virtual Currency and a De-Centralized Virtual Currency.
http://www.fincen.gov/statutes_regs/guidance/html/FIN-2013-G001.html. Centralized Virtual Currencies mean that the Administrator and this can easily include developers etc. are considered MSBs and subject to MSB and AML/KNC regulations. Premined, IPO, ICO coins and likely many instamined and ninjamined coins are considered Centralized Virtual Currencies and subject to MSB and AML/KNC regulations.
For a coin to be considered a De-Centralized Virtual Currency
both the following conditions have to be met.
A final type of convertible virtual currency activity involves a de-centralized convertible virtual currency (1) that has no central repository and no single administrator, and (2) that persons may obtain by their own computing or manufacturing effort.
This is among many reasons why I have limited my Crypto-currency investments to Bitcoin (XBT), Monero (XMR) and Namecoin (NMC) and have stayed well away from premined, instamined, ninjamined, IPO, ICO, etc coins. We must keep in mind that the whole point of Bitcoin was to create a de-centralized form of money without a centralized controlling entity, and not to replace one centralized controlling entity with another for private profit.
Edit 1: If one wishes to invest in centralized forms of money one can buy shares in a bank.
Edit 2: It is not just FinCEN that premined, instamined, ninjamined, IPO, ICO, etc coins need to be concerned about. In the United States there is the SEC, and then there are hundreds of national and sub national regulatory bodies worldwide that could follow FinCEN's lead.
