You can check my previous analysis about his hellish CBOE/CME cycle that suppress/pump BTC price ( and the whole crypto market ) into dump & pump cycle.
If my guess is correct, this dump will stop around 6-7 June 2018 at around 7000-7200 price. and it will continue to pump again.
But since the price will stuck at trend line ... so the highest price for next BTC pump cycle will be around 8500 or 8200. But I think 9000 is the possible price target for next pump.
