... will cost 1000 usd when dash will cost 4000.
I think next year is possible but not probable. My central estimate is q1 2019. What you do in your trousers is of no interest to me.
I am no expert on dash, but consider it conceivable, if unlikely, that it may be 4000 in the same quarter; however, it is at least equally likely that a reflexive cascade of masternode liquidations, or instamine dishoarding, or a high-visibility compromise - take your pick; surely compromise would lead to a torrent of liquidation - will take dash down to double digits, even single, at that time.
