It is better to hold those when bull market is back and then sell for higher prices. No point selling at these low prices unless need cash urgently or believe the project is not good.
Even if you just receive it from a bounty or a free bounty, its better to hold on especially when we are in a bear market. Your work for it will be useless if you just sold it for a less better to wait for a bull again. Sell your bounty token base on your target price, don't be like those hunters who dump the market from the time that coin listed in an exchange.
