If you are losing money continuously with the same strategy, why not change your strategy. Yes, you have to make a good and solid strategy. And also you should know when to get into a trade, and also when to exit from a trade. Make good research on any Crypto you want to invest in before putting in money. Although, losing in trading is normal, but you have to minimize the number of lost you face while trading. However, you have to take a break and detect why you are losing more, figure out the problem, because without knowing the problem, you can't probably find solution.
^ A one or two consecutive losses in a strategy is not good at all, you need to change it and find a better one that suits your trading activity.
There are too many strategies that can be used if you really want it and there is no need to repeat it once you have experienced a downside on a strategy. A good trader should always prefer a few strategies and not stick to one strategy because trading is not just easy of making money and actually, predicting the market price needs more tools to become an accurate one. As I suggest, gain more experience than making a lot of money in trading.
