I notice that some coins that are already in the market are doing bounty campaign again like Credits, Veil Eterbase and among others, do you think it's important for a coins/tokens that are already listed to run a bounty campaign from time to time even if they are already listed in exchanges.
These projects do bounties mostly out of two reasons. Firstly to give more coins out to the community as stipulated in their token allocation for community reward or for marketing purposes where by they seek for more recognition and popularity. So, In most cases, Bounties are inevitable and it does not matter if its a trading coin or not
