Trading is not as difficult as you think
I think it is. Maybe understanding trading strategies and learning how to trade might not be so difficult, but i think becoming a profitable trader is difficult, how many traders out there do you think are making profit, i reckon it is not such a large number. There is a reason why newbies are not advised to start their crypto journey with trading, and it is because of the risks involved in it. This your idea of "simply doing the opposite of what you do", have you implemented it in your own trades, and how successful have you been?
Well, we don’t actually throw immediately our losing strategy without trying to fix it, boost it or upgrade it hoping that it will give us a better trading performance. But if you are losing for years now, I don’t think there’s still chances for that strategy to improve, but it’s better if you create a new one that would be perfect on your trading style and risk management. After all, you know what’s best for your trades, it’s either you keep suffering from the consequences of your losing strategy, or you risk to come up with something new that will suit yourself as a trader.
