This updated look is somewhat better thought out.
I've now set the price per period ratio on the and avoided the use of the log scale. I picked $500/week as a nice rounded ratio. It is somewhat optimistic, though it fits almost perfectly as of last week.
I picked the start of the current price action as being 2017-07-17 and went from the Open for that week.
The end result suggests that if we can maintain current levels of cash injection we could see $40k by the end of 2018. Even if they fall back to a more modest $250/week we're looking at $21k.
Either way if you're a long term investor then perhaps it's not too late to buy in to Bitcoin .
