People should be moving all their volume to Poloniex now. It's the perfect time to consolidate all of the community's volume on a solid trusted exchange like Polo. They even have margin trading now too.
People here do not understand US regulators.
The initial process today is a "honeypot" to suck in all the US crypto exchanges...
The SEC voluntarily gets ALL the data then starts turning the screws...
Where the end point is requirement to operate exactly like a US broker-dealer.
That means complex Tax Slips annually for every account, tax withholding, courses for every employee, etc...
Office inspections by SEC examiners, endless useless administration.
Polo, Cryptsy and Bittrex are really doing only about $200,000/day in volume = $400 in fees = $146,000/year...
To put this in perspective, I paid $246,000 in commissions to Interactive Brokers in 2002...
This is what one medium sized pro trader account might do at a US broker-dealer.
They will all soon disappear once crypto trading moves to Wall Street and ETFs, etc...
Unless they reverse buy a defunct US broker-dealer... and become 100% legit part of Wall Street.
