I don't think that's correct, at least in the USA:

Ebay has $500 Mil per month in profit. That means a total of more than $5 Bil in transactions every month. They can't make $500 mil per month at a capped $50 fee. Look at their cash flow....not possible with a $50 cap on fees.

For dStors, fees wouldn't scale of course if it was a single $1 Mil transaction. However, the composition of MOST transactions are expected to be mostly in the range from $125 to $650. In this scale, $1 Mil total transaction made up of the average price items would scale accordingly.

But here is the differentiator. On eBay, what do the seller and buyer get after the transaction? Nothing but the transaction completion. dStors will raise the value ceiling by rewarding buyers and sellers with STORS tokens that can be spent for upvotes from dSTORS voting bots on either the Steemit or Whaleshares sites. Or, the STORS token can be sold on the Bitshares exchange for FIAT or BTS or any other cryptocurrency. Or they can hold STORS tokens as convertible options to the ICO tokens.
