2- Are you a BTC holder? who bought BTC and hold it for months, Years to be in profit?
3- you tell me.
Number 1 and 2 are the most easiest way to earn Bitcoin, though there's still a lot of method to earn more like investing in IEO/ICO, casino bankroll, gambling, and the list goes on, but these methods has a high-level of risk.
If you know how to deal with investment businesses in crypto space pretty well, then I think the level of risk may lessen a little bit. Nevertheless, any kind of method doesn't automatically guarantee a return.
