Basically, both profits and losses are part of a trade which cannot be separated,
when you make a wrong decision you will lose and that is why it is very important to have knowledge and skills,
but having it does not mean that it will guarantee that we will avoid losses, at least we can minimize the risk.
I can't deny it because basically it is. But someone came up with a plan that wanted to earn a consistent profit of $100 for a $4,000 investment budget. I know futures trading is risky but if they are good enough there then futures trading is also worth a try. But I tend to advise him to trade on spot trades, 100$ can be earned as profit though it is not consistent all the time.
But before that, no one can guarantee consistent profits every time they come to crypto trading. Crypto asset price volatility happens all the time, and that's the most basic problem why consistent profits are hard to come by.
