To make money on cryptocurrency is by doing trading or make investment with any alts, particularly in bitcoin but it needs capital enable to start with this sort of activity. So, for those who doesn't yet a capital like me, you better joined airdrops or in bounties such as signature. As of now this is only I can do but, not yet earning since the start of this year. I already received some token in my previous campaign hopefully it will list in a good exchanges soon.
