It clearly tell us that after ICO and after a specific coin is listed on exchanges bounty hunters or ny other holders were dumping the tokens they have that is why there is a price drop.
This is not something that has to do with bounty hunters, and mind if I tell you that most bounty campaigns usually only hold few percentage of the total coin or token. In this case I would say this has more to do with the whole market itself not being favorable since it is a bear market and even the bigger investors have more part to play when it comes to driving the market down as only their bonuses alone is enough to do that and most bounty hunters even only get to sell lower than ICO price at times which is always the target of the whales.
Hello there, 90% of tokens fall down after ICO now, it's a usual situation, you just need to choose ICO more wisely now, ICO still can be profitalbe just do more researches about it. However if you are bountyhunter just do the same things.
It is even just something with the market currently and in a bear phase for most cryptocurrencies; it is a normal thing to get to see the whole ICO market as well taking the hit. ICOs are still very much profitable but we have to understand that this is an altcoin market and the volatility is always going to be huge which is the reason you should never be investing what you cannot afford to see go down in the short term and at least be more focused on the long term which is actually the main thing anyway.
