Anything you want, within reason :)
Host a website, run a Steem witness, store files, run a game server (e.g. minecraft) etc.
Our only restrictions are:
- Don't do anything illegal
- Don't run a TOR Exit Node (relays are fine though).
- Don't run an IPFS node in our Germany/Finland region (our DC's firewalls get very upset).
RE: Privex now accepts EOS! Order dedicated/virtual servers with STEEM, SBD, EOS, LTC, or BTC - no credit card required
