You're right with saying that the price has increased, but that just means that Bitcoin was a fantastic investment months ago as the price has gone up nicely till where we are sitting at currently. Right now it's a 50/50 situation where I personally wouldn't want to step into the market at current prices. Right now it's good to either keep holding, secure profits, or to simply wait till the price drops to enter the market.
Don't add much value to the predictions made here as they mostly are way off from the reality. Reaching the $800 level, and perhaps going slightly over it to around $820 is the most we can expect to happen this year. I consider the price at current levels already to be a fantastic Christmas gift, so for me personally it doesn't matter whether or not we'll reach $800 this year.
