Do you mean, if I paid 0.01 BTC to buy PRTN, 0.005 will be back as buy order on exchanges??
Yes, and 0.0015 will go to Sev team plus 0.0035 will go to develop platforms and increase the value
What is the usecase for this project?
At first: Ads sales on the website and channels, later: courses sales + freelancers tools
Don't get me wrong, but hard to achieve success in waves platform. I don't know if you your buyback will be an attractive feature here. Even if you have target use case but what is the status of that? Is that in alpha or beta stage? Very rare that a project built in waves will pull it off in the market. Good luck!
