I don't know what Poly is and its fundamental analysis. However, what stands out in the chart is the steady decline of its market price. The general advice is "Never catch a falling knife!' because the falling knife cryptocurrency is crypto with downward momentum and it takes times to stabilize again or it will bounce back. Moreover, no body/ algorithm or institution knows when Poly has bottomed out. Bottoms and peaks are difficult pieces of knowledge but practically impossible to say while it’s happening, or to predict when it will happen.
to be exact I'm sure if this is currently the best way to buy coins
the market will soon recover. bitcoin will continue to improve. this is just a common decline in the crypto currency exchange
