even if i convert it to bitcoin or ethereum, it has to be long term period investment, especially at current market situation. but i think it depends on how good are the project or ico you have participated in bounty campaign, if the project looks promising and has potential to grow, i will tend to keep and hold that token as long as they launch mainnet or beta test, or even until the platform or project are ready to run, i think it is the same case..you have to hold it for long term period for both investment
Doing a bounty campaign is like investing in bitcoin, As the campaign goes and turn to be successful the coin or token you can get is a payment / investment of yours.
Yes, having the bounty payment on your wallet is not just a money to be, you need to make a right decision whether to hold or sell.
