yes I am also one who started from bitcoin with no capital at all and I was able to get a lot of profit from bitcoin, at the beginning I got bitcoin starting from the existence of a faucet and some other events that paid using bitcoin a few years ago.
cryptocurrency really give us huge chance to earn money without any capital.only internet connectivity and computer we could start to work and earning bitcoin.maybe people that join in crypto before 2016 today become millionare.
Even if peoples join now and concentrate much deeoly on bitcoins can become a millionaire ahead. The fact is that how much we learn hard and how we can acquire the knowledge. Bitcoins are actually vast to understand but once you get it, you can really earn a stable income as compared to any physical job.
