I hope I have placed this technical question in the correct section. I simply do not know where else to put it.

This is a question about generating vanity addresses (not mining): generating keys until you get the result you want.

I rent a Ubuntu VPS with 6 cores. This is not a dedicated server. Currently I get a speed of about 2.8Mkeys/s.

My understanding is, that in a shared VPS model, the overall CPU and memory are shared across all users. So I have my own IP but the capability of the resources I use depends on what other users are doing (with other IP addresses). That's why my speed can vary (it has been as high as 4.5Mkeys/s and as low as 2.1Mkeys/s).

What do you think would be the most cost effective way to generate a higher number of Mkeys/s?

A dedicated server with a certain number of CPU cores (how many cores?)

And what's the difference between KVM or OpenVZ VPS's? My impression is that KVM is superior but why?

Thank you.

As the title says. I have used Bitcoin Blender but it closed. There are many scams out there.

I would like a reliable mixer / tumbler.

Many thanks.

Can anyone suggest a website where people can sell their services e.g. programming in exchange for crypto?

I was very impressed by xbtfreelancer.com but they are not allowing new sign-ups. I tried them a few months ago and had the same problem.

If you hire people, where do you post?
