- Volume on online exchanges is way too low: getting 2 million bitcoins is near to impossible
- Therefore the price of one bitcoin needs and will rise, so less bitcoins are needed. But this only happens because of the one time instant demand, and likely pops afterwards. Not really a safe storage of value, when 50% of your Francs are happily converted from bitcoin again in fiat by all the current bitcoin holders.
I disagree: if you buy 2 million bitcoins over a certain period of time x on the exchanges, I am pretty sure the price will settle well above the starting point and not much below the last buy you make (maybe even above, it'll overshoot quite a bit after you bought your 2 millionth coin).
It would be so much fun to execute. Mr. Putin, I'm ready to help.
