It's worth it to collect a coin at this time with a bounty. Because in a few years from now, market volume is rising. In a few years, it will be very important.
actually, I am thinking of months only and not years for bounty tokens to again give profit to the bounty hunters for holding at times like this wherein market value of most cryptos are at their lowest. We should really keep the tokens from bounties for now in order to earn bigger profit once recovery happen.
