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
The even scarier part is that if you do a very high leverage (I have once seen 250x in one place which is insane!) you have like maybe 100 bucks to move and get liquidated, maybe it is just 1k but let's be honest 1k is not a lot in crypto. So, as soon as you invest into a high leverage, you end up being at a risk of losing every single investment you have there, not just a drop, totally gone.
It doesn't mean that the result is a guaranteed loss, obviously you could also make a lot of money if you are right as well. With that much risk and leverage, if you are ever right, a few thousand dollars to your direction could mean tens of thousands of dollars profit instead. Much riskier than holding crypto itself, but a lot more profitable if you are right as well.
