I have seen that different exchange markets have different buy and sell %. Would a day trading bring some profit? Let's say bitstamp sells for less whereas gdax offers more expensive. Would this work to buy cheap and sell more at another exchange?

It seems a easy way of earning money but it doesn't work flawlessly when you attempt to do this. You need a giant capital, you need giant amount of cryptos that you want to make arbitrage etc.
It's very hard honestly.
