Determine the return point D with the harmonic Pattern - BTC

D point :
1-butterfly / Anti cypher pattern (D = 51337)
2-Anti shark (D = 50131)
to me, In case of starting a downtrend it is possible that Bitcoin can modify up to level of 0.5 Fibo

on the other hand,This analysis loses its validity by breaking the resistance of 51,500

Always make your analysis before a trade
It is not offer to trade.
Good luck
