Do you have any opinions about current parameters or fee rates?
Yes. I support BM's idea to refund fees for canceled market orders, but keep the 10bts fee for completed orders. I think it is an elegant solution that will help prevent spam, but will not hurt us marketing wise.
I think 0.1bts is good for feed publishing fee, but will vote to raise it if spam becomes an issue.
I am open to reducing the transfer fee to something on par with bitcoin. Maybe 5-10 bts. Before making this decision final it would be nice to see some statistics regarding the percentage of transactions that are simple transfers vs other types of transactions. I am a very big fan of the deflation we have been seeing the past ten days, and if transfers were the #1 driver of this, I would hesitate to reduce that.
In regards to block time, I think we should stay at 3 seconds. I also would not change the max number of witnesses or committee members.
Those are really all the fees and parameters I have thought deeply about. If there is something specific that we are considering I would greatly appreciate anyone elses point of view.
