At this moment It's not possible i think.
I tried a few days back. But after doing this for 1 time the coin price haven’t decreased yet.
So the chances are lesser than before it was.
But despite this u can do good business with some specific lower graded coins.
But it will be too risky cz they can dump anytime with any price.
So you have to analyze the coin first for 2/3 days.
Than if u think it is suitable for you u can buy it.
But the problem is you have to wait for a period of time because of their small market cap.
But anything can happen. You just have to trigger the right button with a little bit of luck😁
