nobody can sure.
i don't really believe BTC is gonna back to $250, even though if it come true, it would not be too long.
china is gonna raise BTC again if it is affordable enough to them.
yeah and when BTC back to $250 we should be quite happy to buy and hold some bitcoin. because I am sure This will not last long and we will go up to $500

If the price goes down to $250 or lower, it is a good buying opportunity. Bitcoin is more popular day after day. More people are aware of that. It is becoming a money.
