Basically, you sign up on a site like Freebitco. To make a profit from bitcoin mining, you need to have a lot of very powerful hardware. Disclaimer: Cryptocurrencies are speculative, complex and involve significant risks — they are highly volatile and sensitive to secondary activity. There are legitimate ways of getting small amounts of bitcoin for free, so being asked to make a payment is a distinct red flag. So if you like watching videos, why not register on a PTC site?
