does it vary for different coins? I'm asking because if I want to day trade I want to make sure its doable. Someone told me it takes a long time to have a buy go through and a sell.
Before start to buy/ sell you must know take profit and stop loss for your strategy, if you don't have it please don't try take position. Day trade have short distance ( range ) about take profit and stop loss, but some times trader want more and that's why they loss. This is day trader not week/ month/ year ( long ) trader, it's not same at all. Mostly, day trader will close their position in 1 - 2 day even win or loss. Just like that and good luck to you.
