Small VPS

[Adamlm]

Hello, I have a spare and almost free small linux VPS: 1 core, only 512 MB RAM + 512 MB swap (not extendable unfortunately..), 20 GB HDD and only 2-3 ports open. I've been using it as a Horizon [HZ] node https://bitcointalk.org/index.php?topic=551666.0 but now I want to change it.

What do you recommend? Is there anyting usefu or profitable what can be done with this kind of VPS? An Ethereum/NXT/NEM node? Or something completely else?
