I'm still a beginner in the world of bitcoin. I see someone making a lot of money from work like this, he commented on many things in this forum and played Facebook or Twitter to get a bitcoin prize to be exchanged for money. can I make this bitcoin my main job? do all friends have other suggestions?
you can directly and indirectly.
directly is daytrading bitcoin (hard)
indirectly is selling your skills for bitcoin
it all comes to earning bitcoin this or that way
