In the short term the most important thing to do is grow the coin so even a small botnet doesn't overwhelm the currently-tiny network.
What do you mean by growing the coin ?
More miners ?
In every way. More miners, more users, more developers of services, more value, etc. There are only a limited number of botnets and they have limited size, and they have many different uses. A large enough coin can't be affected by botnets. If bitcoin were still CPU mined, it would be too large for botnets to matter. That's the goal. At least the short term goal.
