Actually that depends on situation, but i share my strategy here i always sell half amount of tokens and keep some amount of tokens for long time hold if the project is good.
I was browsing random things on internet and then i know about dark web then i got to know about Bitcoin payment and i was very curious to know about it so that how i know about Bitcoin.
Yes, for me this is the best method to collect coins without risks as you know in trading you need capital but in bounty you just need time but there are many scam bounties so you need to research before choosing any bounty.
I always see the bounty manager reputation and bounty plroject Whitepaper and team to know weather bounty is good or not and i find bounties on different platforms like bitcointalk marketplaces in altcoins bounties section and there are several website like bountyhive, bountyolatform, bounty0x they provide full details of bounties with bitcointalk bounty link so you can research and join.
I faced some problem although they are not scam but their withdrawal fees is very high and in my opinion they are not that much trusted. In personally i don't like hitbtc.
