I am defending the picture, the original isn't mine. I simply reinforced the trend it said. I didn't do the math behind it, as I was defending it. Assuming the trend continues, and Bitcoin evens out. I would assume the price would be the mean of the High/low fit at that time. That's only IF the economy puts out the demand for that amount.
... in which case the picture has no relevance whatsoever. The current trend is a downfall, no matter what types of graphs people draw, and it isn't beneficial for the community to draw graphs in hopes of increasing the value of BTC vs USD, aka to manipulate the market. Whether or not it will turn into an uptrend has nothing to do with the past performance, and it would be better for the community if there wasn't actually an "uptrend". No-one wants to use a currency whose value changes 20% per day (Zimbabwe, anyone?) - the best thing for Bitcoin would be for the valuation to level off, so that more serious merchants can step in.
If that doesn't happen, Bitcoin will turn into a speculation commodity, which doesn't predict a long life. And don't take me wrong, I do believe in the project, people are just focusing too much on the BTC/USD exchange ratio instead of the relevant issue, which is to actually use Bitcoin as a currency...
