As with the passage of time more people are entering the cryptoworld and we can see there are many scammers nowadays so can you suggest any ways where newbies could earn btc without investment.
There was a time I recommend newbies to do faucets, but it is not recommended anymore the best option I can think of is bounty hunting there are Canino sites that offer signature bounty in exchange for Bitcoin and I'm doing it right now, it's easy and profitable for newbies but you have to rank up of course.
