The fast profit will happen when bitcoin will be stable, with that statement it is just right to start investing now with the current price as bitcoin is expected to substantially increase its value in the future, we have to be optimistic as we are seeing people are adopting and that is a good sign of success.
stable mean low profit you can't buy and sell immediatelly because the price were too stable,and buying now is actually not a good idea if you're seeking only for profit and can't afford to lose,the current price is too high in my opinion
