When I checked the balance of my address on xchain.io I noticed, that my tokens (x) match only half of the percentage which they actually should (x/15'000'000 = y, but the percentage z which is given to me by xchain.io is only y/2). So I wondered why that's the case and if I missed something here. Are there 15'000'000 more NVST which is hold by the dev/NVO team? Or why is this?
And if it is like this, will this tokens always stay at the NVO team for the 50% of the fees or are you "allowed" to trade them in the future?

I don't have a problem with it but I just wondered...
