I often see pay rate estimates in USD created by looking at the current 'price' of BTS and just doing a straight multiply to arrive at a number. However, this gives a distorted view because the top price often has so little volume associated with it.
Indeed the entire buy side order book at BTER.com for BTS/USD has less than $200!
This means, to cash out to USD, you have to go from BTS->BTC->USD.
Looking at the BTS/BTC market in BTER, a sell of 12,960,000 BTS (101 delegates at 100% pay rate for 1 month) would clean out the order book completely, and result in a slippage of around 500 BTC total value.
Long story short, on BTER, 100% pay, for 1 month, in USD at current market cap of 35M USD after slippage = ~$200
Obviously this is worst case, since I'm only considering 1 exchange here...
