Bitcoin continued its uptrend yesterday with a short-range. This short uptrend has led to the growth of many altcoins in the market. However, it should be noted that the growth of altcoins can be temporary, and when they encounter major resistance in the chart, they can be accompanied by negative reactions. Bitcoin's significant resistance level is currently in the $ 21,700 range. If this resistance is encountered, it can be accompanied by a price reaction. But if it breaks strongly, the next bitcoin target will be in the $ 23,000 range. Bitcoin's short-term resistances and supports are in the range indicated on the chart.
