Counterparty (XCP), that is trading between .009 and .027 on Poloniex has a TX Fee of 0.1 XCP. That is robbery, a 10% fee on such a valuable coin. C'mon OP, this can't be how you are trying to attract business, right?
The withdrawal fee can never be 10%. It is a flat fee of 0.1 XCP, to cover all the dust costs incurred in moving the XCP around internally. I believe the minimum withdrawal is 3 XCP, so the highest percentage the fee can be is 3.33%. To reduce that, just withdraw more XCP in one go.
I was not aware that there were a lot of dust transactions with XCP. I am just confused as to how every other coin ranges from .01 to .0001 in TX fee an this one is .1 of a coin when this is one of the more expensive ones. Aren't "dust" costs associated with cheaper coins? How does this math work out?
DOGE PRICE : 0.00000217 TX Fee: 0.01 DOGE
XCP PRICE: .011 TX Fee: 0.1 XCP
Are there exorbitant mandatory fees that I am unaware of? Honest question. I apologize for the choice of "robbery" to describe the fee, but wow.
Counterparty is not just another coin. Transactions get send via the BTC block chain, so some BTC has to be sent whenever XCP is sent. Furthermore, the protocol requires the a deposit to be swept into a central account before it becomes available. The cost for each transaction is at least 0.0002 BTC, so an absolute minimum is 0.0004 BTC. But then, a little BTC to cover these costs has to be in each account, so sometimes some BTC dust needs to be moved around before the XCP can be moved, and each time this occurs, it's another 0.0001 TX fee. Sometimes BTC dust needs to be moved more than once, because Counterparty is a little unpredictable in its BTC requirements.
I would say a deposit and withdrawal cycle probably end up costing almost 0.001 BTC each. The 0.1 XCP fee amounts to about this much.
You could say this is his bonus for being the first (and only at the moment) to have XCP on his exchange. Just don't do to many withdrawals, try to combine them in one big one.
