The yellow circle represents the point where you experienced a decline. The white circles indicate points where you regained what you lost. There are no straightforward buy signals, because #Bitcoin is the leader. The more confirmations (white circles/gains) you have, the safer your (swing) trade will be.

You also need to watch for momentum turning around, because you don’t want to 'catch a falling knife', do you? First, we want to see some stabilization and buying pressure (gains) before making a move.
