I have another idea for GOLD marketplace. An estimate of transaction fees on the site when people swap from GOLD to BTC or ETH and vice versa.
TxStreet.com - live cryptocurrency transaction . @wwzsocki posted it but not all people know how to check
estimate fees, network transaction conditions and they will feel uncertain and worry about the unconfirmed transactions or too high fees.
If the feature can be integrated on Marketplace, it will help customers have a good summary on what might go on with their swap process and can better choose which coin to swap will help them save more fees, with better speed.
If something like this will be added, I suggest to also give the opportunity to the user to fine tune the fees (transaction speed), obviously between some limits to avoid the real issues with the transactions.
Right now on Bitcoin network the fees used by the GOLD marketplace seem to be much higher than I'd use (at half of that fee the tx would have been still cleared within 24h, which is fine
for me).
