any volume is being bought.

didn't anticipate that
My advice is to buy it all at the price below 0.11. You will never see Byteball that cheap. Next airdrops bring 10 times less GB per BTC. And GB per GB are only 2 times less. And if Tonych indeed has some plans about integrating Byteball into shops, we can go to the moon.
agree, i see no sense in selling now, the airdrop is being throttled massively, this is the last great drop so in the coming weeks/months it'll seem like a golden giveaway and the best chance you ever had to get a significant amount for free. Add to that the compound of a few more airdrops bringing in more coins for holding than having btc and i'd say you'll get a much better deal if you want to sell by holding everything now until the drops finish
