As long as it is a bounty token, the change is limited that it will not survived. most tokens that did bounty failed to pass through IEO/ICO. The ones that survived got dumped on exchanges. whenever a token in an exchange has no volume, the changes of loosing out is high. it is quite difficult to predict with the outcome will be.
Bounty tokens are not worth much. Just invest in coins that don't go on exchanges yet.
But most ico nowadays are just an event, they just sell coins then aiming for exchange then price drops, then it's gone. It's really hard to find a genuine project that will really make investors hold their coins for a long time
