From the 4hr timeframe chart it is visible Polkadot forming a head and shoulder pattern which is a strong bearish pattern. Also, the value is below 200 MA. Furthermore, the market is very volatile, with BTC dominance. The next dump in BTC can cause Polkadot reaching the next support zone. However, October is always a bullish month for Bitcoin. Add more DOT coin, from the next major support for handsome profit.
