Why I'm trusting my own analysis, 2020/2021 halved scenario

Why I'm trusting my own analysis, 2020/2021 bull run , you can see the trend line was broke , on that time was the real bull run
And if you go back to 2016/2017
You will find the same scenario happened
Now we are just inter the real bull run I'm pretty sure
My only advice is to AVOID AVOID using leverage, the swing price will get your money away from you, use spot trade , don't get greedy
