1. We would have to divide the existing Bitcoin holders in two groups, a) BTC holders that don't know about Dash and b) BTC holders that already know about Dash but are not investing in it for their own reasons.
Since group a is surely too small a set to even worry about (well, both groups are piddling in terms of the real world

) and group b at this point will likely never be convinced anyway until their dear and fluffy beliefs get crushed a whole lot more by cold hard market forces, I completely agree with your chosen strategy.

New users are key.
