The thing about these "drops" is people will liquidate them into real currency as quickly as possible. If the goal is to distribute a currency to as many people as possible (so everyone has a piece of the currency to use) then you have to remove any possible off ramps. But, then you run into the problem of nobody _actually_ being interested in the coin since it has "no real value" (can't trade it for USD)
