As far as I know 90% goes to BTX holders and 10% to the devs in the final air drop.
That's exactly what I typed.
100-10% = 90%.
Edit, to be fair though I didn't say the 10% goes to the dev team though.
The one way that doesn't happen is if 100% of the BTX gets claimed which would be tremendous.
Hahaha I guess if that is what you meant then sure but -10% without the 100 in there is kind of ambiguous. I highly doubt all of the BTX will be claimed. Even accounting for an increase in claimed BTX maybe only 1 million will be claimed by that point. I think the final air drop will be absolutely massive. Although, there is steady growth on the number of addresses which is extremely promising. (about 100 new addresses per day)
