You might see a rush of people buying ETC in order to get their airdrop IF the airdrop is widely publicised. From what I can tell though, most investors are completely unaware of it.
More investors are catching on, I think thats why we are seeing this kind of price action, and the airdrop is still in like 20 days so i think its safe to agree with you that there will be a rush of people. Remember ETC is in top 20, i dont think this airdrop will be overlooked like many others.
