If a project fails its ICO targets and withdraws, how does it pay token bounty?
well they could just simply pay you the token, but that token would be worthless
when they do ICO, they just created their own tokens and sold them in ICO stage cheaply
ICO tokens (on a platform) can be seen similar to pre-mined coin (has its own chain)
that's the reason why so many ICO tokens turned scam, same as coin developer who hid pre-mined coins
If failed, the honest ICO would just returned the fund to investors, the scam one would just run away
I recommend find one, ICO bounty, that pays weekly in bitcoin/etherium or other prominent crypto
