Remember the rule: "90% of the move comes in the last 10% of the time".
In a year, Bitcoin soared from 12 USD/bitcoin to 1000 USD/bitcoin. In total we have a rise of 1000 - 12 = 988 USD/bitcoin.
10% of 1 year = a little over 1 month. The price was 180 USD/bitcoin a month earlier. So in the last month, bitcoin soared from 180 USD/bitcoin to 1000 USD/bitcoin. That's a 820 USD/bitcoin increase in the last 10% of the time frame of 1 year. 820 USD/bitcoin is also almost 90% of 1000 USD/bitcoin.
So technically: "90% of the move (820 USD/bitcoin) comes in the last 10% of the time (one month)."
Which means, the bubble should now burst if the theory is right...
The problem is, I think this time is different with Bitcoin.
