There is a possibility that the price of NEIRO can reach $0.0021, and based on the NEIRO chart and market data against USDT, this target looks achievable, although the exact time of reaching this price is uncertain. Here are some influencing factors:

1. **Current Price**: The current price of NEIRO is $0.00188740, and the highest point in the last 24 hours is $0.0020655. To reach $0.0021, the price needs to rise by about 10-11% from the current level.

2. **Recent Trend**: The price of NEIRO has risen sharply from the low of $0.00003118, showing the potential for rapid fluctuations in the currency. However, it is currently in a slight downtrend, down about 5.69%.

3. **RSI Indicator**: The Relative Strength Index (RSI) is currently 34.41, close to the oversold area (usually RSI below 30 is considered oversold), which means that if buying interest increases, the price has the potential to rebound.

4. **Moving Average**: The chart shows that short-term moving averages (such as 5-day and 10-day) are fluctuating around the current price, which indicates that the market is consolidating. If buying power strengthens, the price may break out to the upside.

5. **MACD indicator**: The Moving Average Convergence Divergence (MACD) indicator shows that the current momentum is weak. However, if there is a positive change in market sentiment, this indicator may also improve accordingly.

Overall, although NEIRO has the potential to reach the $0.0021 price level, market conditions, trading volume, and overall market trends will be the key factors that determine whether it can reach this target quickly.
