I have read the plans for the development of GBX, but I do not quite understand what bonuses will rkt token holders have after the introduction of all these ideas?
Please check page 33 of the whitepaper. Actually GBX have a token staking model that allows for a reduction in trading fees. The only thing that the team will not be doing is token burning
is it a only one use case for token? its understandable about burning - can be lead to some legal problems in future in such direction as price manipulation.
if only the GBX token is burned I don't think there is a problem, because GBX has ICO and circulation of course from tokens sold
If the GBX token is not burned, won't that hamper the development of the token itself?
All I know is that ICO burns unsold tokens so that development can be smooth and profitable.
I recommend to spend a little time and read the white paper, there is a very detailed description of everything, and there are all the answers to your questions.
