It could grow in value if witnesses are replaced. Witnesses would be replaced if they could get percentage of every transfer.
But byteball does not look for such witnesses. That prevents the coin from growing.
Another thing that prevents it from growing is that stupid fixed fee.
It seems you still haven't bothered to read the whitepaper. You don't even understand how things actually work and keep pushing your odd ideas. Witnesses do get a percentages of every transfer, 1/12 of the payload gets to every witness. Regular transfers have 400 bytes header and payload between 150-200 bytes, so every witness gets 12-17 bytes for every transaction. Transactions containing more messages ("payment" is just one type of message) get more fees to witnesses. If witness pick the transaction as parent, they get header commission too.
What you don't realize is that most of the time, witness transactions have had more payload in total that regular users (except in June and July 2018). So, your idea is meaningless because you haven't even figured out how it would actually work.
https://stats.obyte.org/heartbeat.phpIf you hire somebody who does something only for financial gain then there is more likely they will bail on you if there is no financial gain. Witnessing Obyte transaction should not be about financial gain, every witness should have enough other motivations (like having business that relies on working network) to be a witness. So, exchanges could be good examples of that kind of witnesses, they would not earn much from witnessing, but they could earn lot more from fees helping people to trade it on their exchange.
https://obyte.org/Byteball.pdf Chapter 13:
Payload commission goes to witnesses. To incentivize witnesses to post frequently enough, we split payload commission equally among all witnesses who are quick enough to post within 100MC indexes after the paying unit(the faster they post, the faster this unit becomes stable).If all 12 witnesses have posted within this interval, each receives 1/12 of the payload commission. If only one witness has posted, he receives the entire payload commission. In the special case that no witness has posted within this interval, they all receive 1/12 of payload commission. If the division produces a fractional number, it is rounded according to mathematical rules. Because of this rounding, the total commission paid out to witnesses may not be equal to the total payload commission received from the unit’s author(s), so the total money supply will change slightly as well.
We pay only the headers commission and not the entire commission to those who are quick to pick our unit as parent, for the following reason. If we did pay the entire commission, we would have incentivized abusive behavior:split one’s data into several chunks and build a long chain of one’s own units storing one chunk per unit. All the commissions paid in a previous unit would then be immediately collected by the same userin the next unit. As we pay only the headers commission, such behavior is not profitable because to produce each additional element of the chain one has to spend additional headers commission –roughly the same as one earns.
