Masternode is easy way to earn money, but most of the popular masternode is too expensive to setup, example dash, other cheaper MN also need at least 1K, you can easy setup a masternode with low cost for low volume coins and hope it'll raise in one day, but I don't recommend because you need to calculate monthly VPS price and high risks to join low volume coins right now, maybe it's just waste your money and time
I don't do MN in vps because my desktop is always running which I do stake coins as well not just MN. there's a VPS for $5 a month or just to try running it and see what need to be fix in your strategy.
