What the heck is that supposed upper bound, its utterly meaningless...
Anyways this indicates that the price supposedly doubles every 6 months even if it stays on the lowest trendline? Huh, if I have to wait until we go down to 40-whatever but then we're sure to get $100 in like 8 months and like $200 in a year, I guess I'm k with that.
The lower line is the lower limit. Probably the lowest limit possible due to the actual usage of bitcoin at the moment.
My opinion is the lower trendline is growing a little slower (to be expected) than the line shown.
But, the price incorporate the actual value perceived by the buyers and sellers and the projected value in the future perceived by the buyers and the sellers.
On the lower trendline bitcoin is just actual value o little more, so the pressure to the price to incorporate the future value in greater.
This imply the probability of correction higher are greater near the base line than when the price is higher than the baseline.
With the current book of MtGox 10 M$ are enough to clean up 100.000 BTC and bring the price to 158$, double the sum to clean up all other exchanges.
20-22 M$ to double the price.
200K BTC is 1% of all bitcoins possible, around 2% of the actually existing now bitcoins, but given the number of BTC stored in addresses never touched or rarely touched, 2% is more like 5% or more.
Anyone thinking bitcoin have a bright future in the realm of 100K$ to 1M$ (or more it could be more) would be hard presses to not buy when the BTC is very undervalued.
We MUST always remember that bulls runs are born in desperation and die in euphory.
When all run for the exit it is time to enter and when all want enter it is time to exist.
When will see people battling to change their fiat for millibitcoin or microbitcoin, then it is time to spend our bitcoin.
