This would produce the most gains , but if you predict wrong you could be stuck waiting for the price to either come back up or down to get back in. I did this the other day. I sold and bought back in at what I had predicted was going to be the next upswing. However some last second sellers swooped in and dropped the price below my limit. I only do this if i'm sure i'm on the right project with good community support but if not i won't do it. Another thing is if i'm willing to risk all my balance in just one trade. If yes, then i will buy all with my balance then hope that the market won't fail. Sometimes, i don't feel just hitting the all in button because i might lose big in just one trade so it's case to case basis for me.
No, I do not use all my money into one long day trade. Basically the risk of trading is the price of up and down very quickly. Usually, I use and set some limitation. We as traders must be smart to analyze a chart to get a profit. That is because so that I do not get greedy and mad. Should we have a lot of luck not greedy, because up and down a coin that we do not know when it happens. The most important thing is to keep your head cool. Better to profit less than a lot of losses. Do not mess with your emotions. I also never like you coin prices have down trend and I lose, but I understand it in terms of trading. And do not use your emotion for trading. So be patient and not easily discouraged. Do not get greedy and mad when you lose money.
