Is it possible to earn 2-3 bitcoin by working online with out investing in an year or so...because i am not that financially strong to buy the bitcoin
You can sell some of your skills like content writing, photoshop, coding etc in exchange of BTC. Mining is also not practically possible without investment. For trading also skills and initial investment is required. Gambling also need initial amount and then LUCK. even your rank is too low to get any Worthfull work on this forum. So practically it is not possibly to earn 2-3 BTC in an year.
