The last time I mined I'm using VULTR because of the bonus, but now that I just come back here I'm also looking for a better option and it seems this one is a good one, I hardly mine and just getting my IDENA through validation which I have passed 4 times, I hope the same configuration is the same as that of VULTR.
If you are getting idena from validation only i suggest you to give up on your own node and paid servers. You can use web client-
https://idena.io/?view=webclient and shared node from other users - I suggest to visit
https://node.idena.site/ - rioda (community dev) service.
