Given the price held up for 6 months at $6k then lost 50% of it's value to $3k, where it has been for about 3 months now, I don't doubt that the price could drop another 50% to $1,500 in the coming months, but I doubt the price would go much lower than that. I also wouldn't be surprised to see the price first test around $5k before going there. Personally I have buy orders from $1.5-2.5K, as I a capitulation to these levels would be short lived (for example a few months or week).
