BTC--->USD day trading possible?

[Pursuer]

you can day trade with any pair of coins, BTC-USD, BTC-CNY, BTC-altcoins,... as long as they are volatile and as long as you can predict the market you can do it and make a nice little profit every day. and fees should not matter much in this market since the volatility is much bigger than the trading fees these exchanges charge which is normally 0.2% by the way, so I am not sure how Coinbase charges their users, try their other website called GDAX which someone also suggested. it is more for trading.

You can trade Bitcoin for USD on vitrually any top exchange, such as Bitfinex, Bittrex or WEX (formerly known as BTC-e). There are more, such as WAVES DEX, which I personally really like and wish that more people used. Anyway, just search on Google and try one from the first page?
