It is necessary to confirm whether it will fall to the 18K-19K section.
This is because, if it falls below 19K, the altcoins are likely to fall by more than -10%.
Even if it rises from the current price range, there is a possibility that it will fall soon due to a rebound, so it is recommended to see resistance by falling below 19K (BTCUSDT chart: 19695.87).
