I am still confused seeing traders getting thousands of % ROI, how do they analyze it?

Hi friends, many are asking how to multiply small funds... in futures.
For example, I am using a small account here.
I did not learn from anyone, just self-taught and only understand market movements and news about crypto.

So usually I take several positions on coins... for example, I have a fund of 30 dollars. I open a long position on those coins when they are down. Usually, I open 10 lots or 5 lots, depending on the funds. My positions are usually full x75 or x125, with a margin of 1 or 2 dollars.....
After that, if the coin goes up, I usually take profit at 50 percent... automatically the margin goes down... if the coin goes down again, I usually enter again with 50 percent of the existing margin.... Even if the coin continues to go up, I buy again on that coin but the initial position will not go up completely. For example, if I initially enter 1... when I enter again, the position automatically becomes 1.5 or 2... and vice versa if it goes down when buying below the position... that position will go down...

So I trade using only 5 percent of the available funds because I am a holder... just to make some pocket money.

Everyone may have different methods...
Now I will show you some coins that use small margins... but the results are quite good for pocket money.

So use cold funds, okay...!!!

Good luck!
