Great way is to make bitcoin with bitcoin that is trading and renting on trading and exchage sites like yobit and polonix which i use personally i recomend you. but i am not responsible for your investment.
Supposedly if you advise someone to do trades you also have to accompany the tips and tricks on trade. It will show your responsibility. Otherwise that guy will potentially lose money in vain, trading need the experience in predicting fluctuations graph.
Yeah that is right Trading is a great way to earn Bitcoin, but it is also a great way to lose your money. Suggesting that you do Trading is not wrong, but members must be aware of the risk involved with it because there are so many thing to learn yet you still have a chance of not earning anything, that is how a big of a risk you are entering. It is not as simple as buy low sell high as you think.
