Max keiser changed his prediction for this rally from $300-350 to $350-450. Its really hard to do any technical analysis on btc when its after beating it previous highs. The price on average has risen 10 fold every year since its inception, so going by that we might see btc at $1000 before the end of next year. As for the current rally who knows, the Chinese are buying btc like crazy. But one thing is certain, day traders don't make any money unless they sell at some point so a crash will happen(how big or small this crash will be is again hard to know).
