If it were a first-time test with a small-amount, I think there's an option to categorize without a fee, then the 10% would cover any paypal fee on my end for for regular / larger amounts...I think about 4%? May change if higher... Also covers any trading / timing / hedging / reserve risk I decide to take. Structured ID requirements should be developed. For example, let's say no ID / etc up to a monthly USD amount equal to the number of forum posts in your profile?
So, final cost to you is:
bter mmc/btc and bitstamp btc/usd + 10%
Spread will benefit me, so:
Bter MMC/BTC BID X Bitstamp BTC/USD BID = MaxMine MMC/USD BID
The 10% covers transfer fees (may change), and development.
