$BTC has reached the short-term support. The current rebound is a natural rebound caused by long stop loss and short stop profit. In addition, the transaction funds will be even more sluggish on Friday. In the short term, the support position of 68,800 will be seen. If the support is in place, it can rebound upward on Saturday and Sunday. If it falls below, it will continue to look for a lower support position of 66,800.
