It's not a rocket science, Bitcoin drops -85% every bear market followed by huge bullrun.
So we should expect 82% - 85% drop from last ATH and based on our previous analysis bitcoin must retest 10k-12k .
High chances of bottom in Aug - Sept(the usual booth month) because of the MTGOX repayment of 150k bitcoins which would cause massive selloff of BTC.
I hope this information finds you well and help you make right trading decision.
