is the total volumen of swisscex 3 bitcoins/24h , joining all trades from all coins together? it seems too low, I'm just asking, because i cant believe it, and I think I'm worng

Yes. Thats correct. I still dont understand why xchanges in somestrangecountries run by whoever geht tons of btc blown in their wallets while this 6 week old exchange with perfect service, support, great matching and payment engine - Based in switzerland, the country of money and correctness - is ignored ?!
But time will tell and sort out these who dont be stable.
I love it to trade there and always mention Swisscex.com as my first choice.
it seems a well made exchange, I tried to deposit and withdraw some coins, and it works ok, but without volume ofc, and nowdays the volume is all that interest in the market
