I don't know if this has already been asked and answered. And 200 pages of forum posts is too much to read. And search terms are not easy....

How can I find out the projected cost of auto exchange from any coin to any other coin?

For example, Let's say I'm mining Monero and I like Ethereum, BTC and LTC. I want to choose the best auto-convert I can to one of the coins that I like. So I want to see the projected/estimated total cost (loss % taken by all fees during auto-conversion) to any one of my desired coins. Then I can choose the best coin I want Monero auto-converted to.

I'm also assuming that not all coins are immediately convertible to all other coins and perhaps has to first have an intermediate conversion to BTC or some other coin or an intermediate conversion to a common coin if the complete conversion to my desired coin can't be done all on a single exchange. The projected/estimated costs of this kind of auto conversion should show the total loss % of the conversion no matter how many conversion steps it has to go through. That will also help identify poor choices for auto-conversion.
