Well, you can distribute them in batches. Like 10k person every month. Let's say there's 10mil coins. First month: %10 of all coins (1 mil) to 10k person, each one gets this %10's %1. 1st person: 10.000 2nd person: 9990 3rd person: 9890 .... Second month: %10 of this 9 mil left ... something like that would be ok. I guess.

make a website, you can't hold a giveaway here, and hand it out. Nobody has done a giveaway before that has been worth anything. Try and monitor IP addresses, but otherwise be generous. Try and get rid of 90% within a couple of weeks. It will pay off. *Edit: less than 200 people holding will get you to an exchange in no time. **Edit: but of course your goal is not explicit. If you want to make money, follow the above. If you want to make a coin work, spread it around to more people but just as quickly. Don't let people get bored waiting for a few coin-crumbs.
