Thanks.
2GB RAM is a steep requirement, especially for Linux, unless there is a way to install multiple nodes and just specify different ports in one VPS. I think this might be one of those coins where you need at least 10 nodes to make a decent passive income from it.
So you don't need 2GB, and you can certainly run other MNs (from other coins) on the same server.
I know one company offering $5/month Raspberry Pi hosting which is about the same as a VPS without shared hardware.
