Hi Friends,
Is it possible to do BTC--USD ( not any other coins) day trading? Which platform will be good for this?
I tried in coinbase but their fees is too high. I tried to do with 1 BTC and I end up loosing money. I sold 1 btc and they charged $80 then when I bought back again they charged again $80 so instead of making some money when btc price increaased about $150, I lost $10 because of fees.

So, is there any other platform that charge less fess so that at least I can make money if btc price increases about $150 or so?
Many Thanks

If you have a Coinbase account use GDAX instead. It's their exchange and has lower fees (0.25% taker and 0% maker fee). You can transfer your money/crypto from/to GDAX instantly with no cost.
