Due to a parity issue (50 here is even) we need to adjust username90's solution. In particular, a sequence of consecutive integers of even length has a half-integer in its middle.
In this case, let's consider the sequence of 50 consecutive integers 16, 17, ..., 40, 41, ..., 65 where 40.5 is in the middle and the sum is 40.5 * 50 = 2025. Subtracting 2009 we get a supposed erased value of 2025 - 2009 = 16 and this indeed correspond to a valid solution:
16, 17, ..., 65 => 17, ..., 65
We also could've considered the sequence 17, ..., 41, 42, ..., 65, 66 centered at 41.5 and this would've led to an erased value of 41.5 * 50 - 2009 = 66 which is another solution:
This conversation reminds me of Reflections on Trusting Trust, an interesting short paper originally given as a Turing Award acceptance speech: http://cm.bell-labs.com/who/ken/trust.html.
100x back in a few years? So the market cap will be >1T, and Satoshi will be the richest man (?) on earth? Don't think so. Maybe 10x, and the chance of this is probably not great enough to balance against a crash.
Good call divesting some of your BTC in favor of physical assets.
Nitpicking: I should point out that far fewer than 1.2 million -- more like 35,000 these days [1] -- die in traffic accidents, although there are many injuries.
