In regards to hunters, i do not think dump off is what is actually done.
Bounty tokens are sold for value, not dumped.
It is true that volatility is high and risk of doing a fake Bounty is enormous, but if you calm your nerves. Do your research, there's alot available Bounty that is positive.
Some are never sold because they never get listed or get listed on shitty exchanges with no volume.
This will never change if hunters will accept shitcoins or promises of shitcoins instead of valuable tokens.
Tell those cheap devs that if they want their project to be advertised they need to pay some real money.
