I think it also depends on the timing as @Swa said. Fortunately, I haven't lost much money so far but I am too scared to do multiple buys and sells in a single day to be honest. Looking at the exchange dashboard is like watching a wild west movie!I didn't do this full time, but I've "lost" money trying to buy low sell high. If I had just let my btc be, my "investment" would have been worth a bit more.
