Strategies are not perfect at all buy once you have this you can expect to have a more profitable trades since you are doin this on a more responsible and discipline way. Learning should not stop from one strategy only, create more as much as possible and adopt what works for you, losing is very normal.
Not only that you could change them based on the market situation, but you could change them based on your own preference as well. This allows people to see changes even in profit situations as well, rare but it does happen. Why? Because, if you are required to be very quick and in front of the PC for you to profit with certain strategy but you can't be online all the time, you could change it, or if it requires you to be patient for a long time and you can't then you can change it, even though it was profiting you.
Being flexible in trading does help people out a lot and it is one of the most important parts of becoming a trader in the crypto world.
