Hosting multiple MN on one VPS is not in the interest of the network.

The network needs distribution to flourish. Which means all a y'all miserly bastards need to pay up for that single VPS per MN.

You'll save 20$ a month by hosting 5 MN on one VPS. Is saving 20$ a month really worth risking your future as a DAS holder?

DAS atm has a high enough ROI to let you profit even when running each MN on a separate VPS. Don't be the Scrooge McDuck in the room. Get them nodes running all around the globe.
