Is it possible to mine Waves without a balance?
You do not mine , if you have your own Node you can forge the transactions of the platform.More waves on your wallet-node means more possible blocks to forge and more TX to receive.
You will need a minimum of 10000 waves to run it.
Hope that helps.
Yes that helps a lot, thanks

.
This looks like a very promising project, and Sasha seems to be making a lot of progress. Hopefully this will get listed on Poloniex sometime soon too.
No problem.
If there is a listing on a HVE will be very big news.
My hopes are the same as you.
