Looks fine and potential, but I have a small worry on risks of losing my coins.
When the MANO price rocket to the Moon, the owners of shared masternode might go away with all coins hosted in their services.
Any ideas about this theory?
I can see your concern, as it will definitely disrupt the business model of providers currently offering shared MN services. However, they could potentially already disappear with your coins at any time.
If you are using a reputable provider they would have (in my opinion) proven their trustworthiness, as they are, and have been, responsible for what would be large sums of money if sold. But yes - as you have noted, there is an element of trust.
