about polo i think right now there is not enough volume in okcash because nearly no one selling big ammounts at this level (would be really not clever to do)
and polo recently do not add many new coins (right now they do sooo much volume with ether, just today over 49k bitcoin)
so i think first price of okcash has to rise much more then what it is now, and then there will be more volume at some point.
and then exchanges like poloniex will add us.
thats my opinion, about an exact time its hard to say. Let me guess.....i say 6 months from now:-).
Let's say I've been around this game long enough to see things and hear some rumours before others. Nothing will be delisted or listed on Polo while ETH is in pump mode, Busoni would be mad to take down the site even for 5mins while $15mil is flowing though his exchange.
But after ...
As for volume, volume increases with price. OK is too low to risk trading any decent amount, some whale is just itching for someone to plonk 1mil OK on sale and lose it in a flash. Get it to 1000 satoshi and Polo will list it and volume will be cool. I trade a bit on all exchanges, but only if I know I can get back more. There have been a few spikes on Cryptopia and YoBit, while sells were at 200 on Bittrex .. that was fun
Yeah everything with Eth is crazy!
I've watched some sell orders 10% higher than the going rate get snatched up due to their size. Seller beware haha.
*** Curious, in the zero sum game we play, what will Eth winners do with their new BTC?
