Primarily, bitcoin is the reason why anyone is talking about cryptocurrency. It is one of the most familiar and generally trade at the highest cost. For me, it is not just a currency use for different transactions but also presents an attractive options to get a hold of cash. Regardless of its ups and downs, the technology behind it could have a long-lasting impact as a medium of exchange. But still I can't predict if it is really stoppable or not due to its unexpected movement.
Sure thing bitcoin can be a source of income for many in the community, many had so much expectation with bitcoin in taking them out of poverty, but in my opinion not all can sure earn bitcoin, because of the need knowledge for it, not all can invest in bitcoin because the price is high many can not afford it, but at least you had adapt to it,
