Tonight watch, hang up, if 99K doesn't break, you can short for the first time, if 103000, you can short for the second time, near the previous high, you can take a wave short, but for now, you cannot chase long or short, the most favorable situation for altcoins is after BTC surges and enters a BOLL daily level sideways, if BTC consolidates for more than three days, you can consider adding some mainstream altcoins.
