What price Bitcoin will be be trending at when the bottom is in I couldn't possibly call at this point in time but mid $200 range seems like a likely bet to me and the likes of Risto will be forced to reassess their 'exponential mean growth line' speculating model. When this time will come I don't know, might not even know about it when it happens cos I most likely won't care.
So you're predicting a prolonged downtrend? I can see bitcoin going down in the short term, but I think we'll see more growth in BTC services this year, which will in turn, attract fresh blood into bitcoin.
Let V(t) be the fair value of bitcoin at time t according to MatTheCat. Let P(t) be the actual market price of bitcoin at time t. MatTheCat will be a strong buyer if his perceived value of bitcoin is greater than its market price:
V(t) > P(t)
His perceived value of bitcoin seems to obey the empirical relationship:
V(t) = P(t) / 2.
According to my calculations, MatTheCat will be a strong buyer for P(t) < 0.
