The fear of dumping often makes the project team fear or avoid the payment of hunters until sometimes after the exchange listing. I wonder why the team make themselves restless on an easy thing like that when they can easily conduct their bounty with bitcoin or ethereum for payment. That will safe them of the fear that the bounty hunter will dump after the exchange listing.
it's natural because the Bounty Hunter doesn't want to think long, after what he got he would want to immediately sell it, because what I know is that the bounty hunter wants to get immediate results from his work that sometimes months that month. different from the investors of the project who want to benefit from price increases.
Not my criterion in holding coins from bounty results for a long time, the longest I have held in altcoin only within two months after listing on the exchange. on average for now I only get shitcoin, so if I get a valuable coin it's happiness and (toast)

. due to the fact that currently accepted altcoin there is no potential when the market conditions are bad. If you can hold altcoin in the long run that means you are great at taking risks.
same here , i dont also like to hodl my coins for a long time but i love to sell them as soon as poosible so that i can enjoy my hardwork from working a long time in a bounty that i joined .
short or long term , both are still have risk . once we enter the world of crypto we are already expose to many risk . also we all have a fear of dumping , that is why i choose to be a short term hodler/trader but for an ico owner its their responsibility already if their coins would dump or not .
