I just found another coin called Mano coin, which proposes to provide trustless masternode set up in a one click fashion. Its a new coin and project appears in beta, but not sure, trying to get current information on the project and price on the coin.
And although this service line is already supplied by Gincoin and soon to be supplied by Apollon coin this appears to be a growing niche. There are several trusted shared masternode platforms, but these three appear to be the first trustless platforms and two of them Gincoin and Apollon have cold wallet set-ups, the set-up of this third one's wallet is unclear to me.
