But trading on Probit is just only started and now it is too early to speak about results and trading volumes. But I see that trading volumes are increasing. Now they are more than 5 BTC a day. But the price of tokens continue to fall. May be bounty hunters started to sell their tokens.
Also the airdrop distribution is at 1 november, I think price fall is the investor's own doing, has nothing to do with airdrop/bounties.
