ARB is a pretty good trading method and it only requires us to work hard to find exchanges with low prices. Stakenet does have users selling coins at a low price but the volume is very small. After clicking on the link and watching the video, I found that only a few people traded in very small quantities. Once bought, we can only buy from 4 - 6 $ and absolutely no available sell orders. So trading ARB is quite difficult when using stakenet. The team should promote marketing to gain more users and increase the volume of exchange.
The video shown only show cases a BETA. The DEX itself is not even out yet, and the DEX Aggregation implementation will pull order books from other DEX's inside the Stakenet DEX, which will make sure there is LOADS of liquidity
