Overall there is a positive sentiment about circle buying polo. I dont think their userbase is going downside because AML/KYC strengthening . Goldman has long business experiences and they know how to cater customers (sadly this was the worst part with poloniex). So i see polo getting a revamped improvement soon.
Regarding price action on steem, i think the outage at poloniex withdrawal is temporary and almost anyone knows it too. This sort of tech outage creates arbitrage options but here its not the case . I think very few will try to sale out polo steem . Hence there will be little or no dip (thats just my opinion) .
Thanks for your article .
