If this is a daily line, $BTC would be great, but it is only one hour, and the level is too small.

Since it has already fallen below 111920, I won't act unless there is a buy signal on the right side. Some people believe that 110,000 and 108k can be bought on dips; a rebound is possible, but it is difficult to place a stop loss, so I decided not to act on the left side.
