Any one of us is doing all he can do to earn more bitcoin nowadays. Even there are lots of ways to earn bitcoins, still it is hard to earn but that is reality. For all the ways to earn bitcoin, I think trading is the best and most legitate way to earn bitcoin. Because bitcoin is pumping too much, we need to be wise in trading because it may cause loss of profit if we did it wrong. Trading is the best but it can be the hardest and the most risky way to earn btc because it needs money to buy some coins for trading and it needs to be updated on every price change of btc but earning btc really needs patience, perseverance and hardwork.
