Not sure if that RING is the right one though but it can be mined I suppose.
But do you mean the standard droplet of digitalocean is enough?
The ring coin I was talking about is a different coin than the one you provided. This is fresh coin not even listed on coinmarketcap yet, and you can read about it here:
https://ringcoin.tech/Being honest I gave it only as an example - I used my vps to mine it because I had free resources and wanted to check how mining via VPS can looks like. Unfortunately, I am not able to say about the profitability of mining because ~ 4 coins that I have mined are not listed on any exchange yet...
Nevertheless, I think mining with VPS is very expensive. Cheap VPS for a 5 - 20 dollars usually have very weak processors and for a reasonable one you have to pay a lot, so it is probably more efficient to mine with a regular PC, especially if it has an AMD processor with several cores
