alright then think about those who bought it around 1000$ mark thinking that the price is gonna reach 10000$ mark and suddenly found themselves below 500$ mark 
If they think that the exchange rate is going to go to $10,000 and they were happy to buy one bitcoin for $1000 then they should be even happier to be able to buy two bitcoins for $1000. Instead of turning $1000 into $10,000, they can now turn $2000 into $30,000.
Your math sux!
