Today's rise in Dogecoin price is primarily attributed to buying signals on the Robinhood platform and a decreased interest in the dollar. On April 6, the price of Dogecoin increased by 7.5% to $0.186, surpassing the overall crypto market's gains of 1.71% on the same day. The weakened dollar has led to a boost in risk appetite, reflected in the bullish movements of Dogecoin and other meme coins, indicating a growing risk tolerance among traders. Meme coins are considered highly speculative investments within the cryptocurrency sector due to their minimal intrinsic value or practical use, placing them at a high-risk level compared to traditional safe-haven assets.
