There are lots of cryptocurrency are created in this situation but still very some of them were interested by the people to invest so how to promote the remaining coins to reach the people to invest.
Promotion is really necessary for every cryptocurrency being promoted and there are actually lots of ways to promote. Social media would really be a big help. You could also advertise online but I guess it is still important to educate people first about crypto currency because they may read it but it might be hard for them to notice the use of it.
