Polkadot (DOT) is facing significant challenges as it struggles to maintain its position above the $4 mark. On Tuesday, the cryptocurrency fell back into the red, with buying momentum waning as the price neared $4.50.

This decline highlights the ongoing volatility in the market and raises questions about the sustainability of recent gains. Market participants will be closely monitoring DOT's performance to assess whether it can stabilize above this critical threshold or if further declines are imminent.

Investors are advised to stay informed about market trends and exercise caution in their trading strategies.
