True but it does keep script kiddies that don't what they are doing from flooding the exchange with .0001BTC trades.
Someone that knows what they are doing and is automating smart trades is a different matter. We could use the volume increase.
Nope so no bots on exchange either.
It doesn't mean a bot can't be made to work with atomic-trade though. For example, you can program the bot to issue trades right through the web interface using site scrapping techniques. This is exactly what I did for mintpal despite them not having a trading api publicly available.
I haven't bother with atomic-trade only because the volume isn't there.
