You can make money even in just a matter of seconds but that would be risk and will be using a bit high leverage. But I think you were referring to day trading? Honestly it depends on how good you are at trading and analysis, some people could lose a lot even in day trading because of bad analysis.
Many of my friends also said that making money in day trading in just a second is possible but the risk is too high that only those with high-risk tolerance could possibly make it. Actually, I haven't tried it because I don't have yet the amount of money that I could be willing to lose in just a second but I honestly wanted to try it, not solely aiming for a high or great profit in just a second but at least I could try it and learn from it, and as a trader, it could be a great experienced.
The truth is that as soon as you place a long or short order with the help of leverage, profits and losses will begin to show and convert instantly and as described, the trend is in line with the prediction that it only takes a few seconds to close the order. Maybe for us, these are games that are thrilling and don't make money very often, but for the pros with a long battle history, mostly use a lot of screens for bitcoin chart analysis, with pretty high leverage and lightning order placement, all are enough to complete their one day profit, it's really fun and worth a try but don't get addicted
