Eh, anything could happen. We could hit $100, $250, or even 1k. It all depends on supply and demand.
realistically it will most likely not go below $300 this year, but that doesn't mean the price will not try to test the lower $300 price levels. bitcoin will never stop surprising people. weird things can happen with enough panic going through the markets.
300$ ? really man no i don't think price can go down to that level with upcoming halving lots of other news like you may see short term rise after DAO token distribution get over and those tokens come into the market.
