It's not impossible to reach 10$ per onion while the airdrops are still happening. But once airdrops are done, I would assume a dramatic price drop. Then again it comes down to the community not to sell ur bag all at once.. But I can't see any possible scenario where the price won't drop after the last airdrop, unless some kind of incentive is set in place by the devs.

Also we would need some real life use for our beloved onions. I guess deeponion's own forum could become a platform where community members start using onions as payments for services. Where to go from there?
