Question about the actual, practical exchange rates on the site, since I'm seeing a discrepancy.
Let me provide some examples.
I converted 0.13 XMR at a quoted rate of 0.00304009 BTC per XMR, which should come out to 0.00039521 BTC.
I only received 0.00029402 BTC.
I converted 0.07 XMR at a quoted rate of 0.00304009 BTC per XMR, which should come out to 0.00021281 BTC.
I only received 0.00011217 BTC.
Finally, a larger amount:
I converted 11.43664499 XCP, at a quoted rate of 1.16841180 XMR per XCP, which should come out to 13.36271096 XMR.
I only received 13.32958171 XMR.
What is the source of this discrepancy? Is there a way to correct this discrepancy in the quoted rates on the site?
I'd like to be able to have a better idea of what I'm actually going to receive when I make the transaction.
This seems to be a separate issue from the fluctuations of the exchange rates. There seems to be another cost in there (a fee?) that isn't being made visible to the user before the conversion takes place. If it's a fee, it'd be useful to have the fee baked in to the quoted exchange rate, or at least calculated and displayed for the user before the conversion is made.
Hello mmortal03,
Most of what you're describing is precisely the miner fee. The amounts you are doing are very tiny, and thus the miner fee will look big in percentage terms. For example in your first case, you expected 0.00021281 and received 0.00011217 which is a difference of 0.00010064. 0.0001 of that is the miner fee, so in actuality the discrepancy is 0.00000064 (in other words, not significant). This final amount difference is likely caused by a small change in the exchange rate from when you clicked "start" to when your coins actually got one confirmation in our system and processed (which may be a few mins later).
There are no other fees other than the small miner fee, so for any transactions more than just a few pennies, you should not have this issue at all.
Note: If you ever need a precise exchange rate that is guaranteed not to change from when you're quoted to when the exchange occurs, use the "Fixed Amount" transaction feature, which gives you a 10 minute window to deposit and if you do so, you will get exactly the rate you were quoted at the start.
