The following are reasons why i think its a bad idea to stop been a bounty hunter
1. Is it just me or it happens to others too?whenever i give up on something thats when that thing will make a good turn, the moment you give up on bounty thats when good projects will come around and you will lose the chance to acquire some tokens
2. Many keeps complaining about how bad some bounty projects are but if you keep choosing projects and you keep failing you will end up been a lot smarter when choosing next time unless you arent ready to learn.
3. Who says altcoin season wont return?many projects seize continues progress because of no altcoin season,i called these projects 'weaklings' but still there will always be good days no matter how long bad days stay around,altcoin season might take longer to come but im sure it will,what about you?
Will try to answer your question
1. When you and others leave the altcoin bounty, those scammer who run or create Fake/scam ico will be less and there will be only legit bounty appeared, that's why you will miss good ICO/IEO.
2. True. You and others will learn the lesson, but fyi those scammer are clever too to make you and others falling to their trap again.
3. It will, but no one can predict it.
