As you said, it's a free token. Whether you sell it at low or high price, you don't have capital for it so its still a profit.
I don't really have a game plan to make most profits, as much as possible I don't count my profit and its just right amount. If you will aim for "most" you are likely to get out of your boundary and can do things that isn't right.
right what you say in situations and conditions like now we also have to be smart and thorough in following the project because now many projects that only contain fraud
That's the reality that many of them are fraud and this is why every bounty hunter should be vigilant choosing one.
So many scam icos but it looks like that has already reduced. but the problem is not so many people are aware about how to do that. Mostly of bounty hunters don't even care about that and they are blatantly joining in any bounty.
It surely has reduced for a year now, 2018 was full of scammy ICOs and even that's really a bad year. Investors learned that they shouldn't be brought up by hype especially with ICOs.
And because of that, if there will be no investor interested to those ICOs, the bounty will suddenly stopped.
