For the past year, we've been operating without any scams or issues. As for volume, there are no limits; you can exchange up to 1000 BTC without concern for the volume of listed coins and tokens.

You can begin your exchange without prior calculation and send any amount. Calculations will be done upon receipt. If a user sends an incorrect amount to the address, as long as the deposited amount is sufficient to initiate the exchange, it will proceed accordingly.
