Edit: also the amount of held bitcoin will probably increase even if the buyers of your coins sell according to your plan (I haven't done any calculation on this, just my hunch)
There will be lag of course, but that is just the nature of the phenomenon, which will happen again and again. Bitcoin is scale-invariant, which means that the ones hoarding 10000s of bitcoins in the early years, sold into the 2011 bubble and bought their mansions. The ones buying like mad in early 2013 (me included) can now sell and be set for life. The ones buying 10 bitcoins now will have to wait 1-2 years. In each of the events the number of people is larger, price of 1 bitcoin is higher, number of bitcoins bought and sold per person is smaller, but the aggregate number is the same, and the influence to an individual person's life is pretty much constant (=equally life-changing )
Barring a disaster, you think 10BTC will be "life changing" in 1 to 2 years?
Will the equivalent of 3M USD be life changing to you? Then yes.
