So by your logic Walmart should sell cyanide, heroin, and nukes? I guarantee people would buy them.
I missed the part where I was comparing cryptocurrencies to highly illegal substances and weapons.
If I were to use an analogy, I'd say exchanges are like unregulated roads in the middle of the desert and you're barking at the road because everybody can get on that road.
To further that analogy - a road CAN become congested and worthless to travel on when filled with crappy slow cars.
An exchange is not like that. We can have 8 great coins and 400 worthless piles of crap. The piles of crap do not detract from the other "good" coins.
It's not even like putting a good store in a shitty part of town. The bad crowd would keep away the "higher class" shoppers. It's an online exchange. The presence of shit coins has no effect on the others.
I've heard the argument that allcrypt has crap coins so it's a bad exchange, but I just don't buy that.
We offer all coins a chance. It's not up to me to judge who is "worthy" and who isn't. If only 3 of the coins we host ever "make it" - it won't be because of the presence of, or the lack thereof, other coins.
