Its very intersting but how it works i mean i have stakes with my name and wallet so afther seling i change wallet or what ,if yes then how we can be sure seller would change wallet?
No man, you don't need to do anything. You continue working on a bounty as you worked. No need to change wallets, etc.
You should definitely try for experience.
All that a hunter needs to do for stakes depositing is just to click on [deposit] button here
in the line representing the name of stakes, which he has earned.
