If you have not prepared for money till now to invest in this project and you want to get some coins then you can get through their referral program. They are giving 5% referral commission.
I also want to earn some tokens for free. I can promote the ICO and can get some investors to the project. It is a very good idea by the enkronos project that they have started the referral program for us. It will give us a very good income along with our investment.
Yes it is a good idea to have a referral system in the project. It will not only benefit us but it will also benefit the project as many people will start to promote the project and they will bring a number of investors to the project to invest in this project.
