It seems that the graph you provided can provide clues to the movement of bitcoin prices this year seems likely to fall and maybe 2019 will indeed start to wake up and will start doing price recovery.
No, please dont consider it in this way. No graph can help you to define the movement of bitcoin in coming days or months. Things are quite fluffy in here. You cant predict the next move by bitcoin through overseeing and making patterns in past. Bitcoin is always happy to give surprises and you might have some bigger in coming days while you were thinking it bad.
