I think that there will a decline in price but it would be as bad as you suggest. BTC might get baco to high 900's or close to 1000$'s but I am not convinced that it could be any worse than that.
but i do not think that we are going down from 1200 USD level. i think the increasing trend of bitcoin will continue for a long time and hope that this time the price of bitcoin will easily cross 2000 USD level.
It all depends on what decision will be made on March 11. If it is positive, then you can wait for the price to take off, and if negative, then there will be a fall
