A post shows that ZBT was part of a HODLer-airdrop: “The total amount of this airdrop is 15 million ZBT, accounting for 1.5% of the total token supply.”
Another post claims ZBT listed with total supply of 1 billion tokens, initial circulating supply ~220 M (~22%) at listing.
One post warns of heavy selling pressure: “$ZBT dropped 50% online, the top ten addresses sold some.”
Another post: ZBT completed a buy-back of 26.3 million tokens (~2.63% of total supply) as of Oct 23.
